Istanbul-based ANG FAST manufactures rivets and bolts using cold forging. We don't sell from stock — we work per order, delivering both standard products and custom parts built from our own tooling with the same engineering discipline.
We don't sell from stock; every order is produced to project specs. Common norm parts (DIN, ISO) are produced on demand, and project-specific designs are produced with custom tooling — rivets Ø1-14 mm, bolts M4-M74, by cold forging.
Round head, countersunk, semi-tubular, stepped — to DIN/ISO standards or to your custom geometry, produced via cold forging.
Hex, socket, torx, flanged, stud, anchor — common norms or fully custom, by cold forging for high-strength applications.
We receive your technical drawing, intended use, material preference, and order quantity. If the design needs refining, our engineers join the conversation.
Fast with existing tooling, after manufacturing if new tooling is required. Dimensional, material, and strength tests are documented and shared.
On our cold-forging or hot-forging lines, using the method best suited to the part's diameter and geometry for repeatable quality.
Every batch passes quality control and is delivered with a full report. We arrange domestic or international shipping per your preference.
We don't sell from stock; every batch is produced specifically to our customer's technical specs and approved drawing. This applies equally to standard products in DIN/ISO norms and to custom parts developed from our own tooling. Whichever you need, our engineering team is with you end to end.
In common rivet and bolt norms, we produce exactly the quantity ordered — with material and coating options to suit your request. Not off the shelf; every batch is fresh production.
For problems a standard part can't solve, we start from your technical drawing or a sample and build it from the tooling up. Geometry, material, and tolerances are designed to your project.
Looking for a standard norm part or a custom design for your project? We're here for both — share your request and we'll deliver a quote quickly.
Request a QuoteIn fasteners, the manufacturing method directly determines the final part's strength, cost, and reliability. At ANG FAST we use cold forging. Compared to machining (CNC turning), the advantages are decisive.
Cold forging aligns the metal's grain structure with the part geometry. Result: 20-30% higher tensile strength than a machined part of the same material.
In machining, fibers are cut; in forging they follow the part shape. This is especially critical for fatigue strength.
No chips means nearly zero material waste. Once the die is built, per-part cost drops significantly compared to machining.
Cold forging presses produce 2-4 parts per second. CNC turning takes 30-60 seconds per part. Real advantage at scale.
Forged surfaces are smooth and non-porous. Subsequent coatings (zinc, Geomet, Dacromet) adhere far more uniformly.
Practically any custom head form can be made with die design — countersunk, dome, stepped, double-head, grooved, concave. Most are costly in machining.
When machining? Depends on part diameter and geometric complexity. As a rule of thumb, for small-to-medium diameter fasteners, orders under 50,000 units may not justify forging tooling cost. For parts requiring fine final detail (custom thread profile, tight tolerance, fine machining), we combine: forging + machined finish.
ANG FAST has a production infrastructure structured to handle high-volume, repeat orders. From the in-house tool shop to the cold-forging lines, our processes are planned around your project's volume and delivery schedule.
Our cold-forging presses are capable of meeting high-quantity production quickly and consistently. With multi-shift operation we align with your delivery schedule.
Tooling for custom parts is prepared quickly with our trusted solution partners. This flexible structure enables production across a wide range of geometries and reasonable sample lead times.
Rivets from Ø1-14 mm, and bolts and other fasteners up to Ø74 mm — a wide product range from a single supplier.
We work with steel, stainless steel, brass, copper, and aluminum alloys. We determine the material best suited to your strength, corrosion, and weight requirements together.
A precise capacity and lead-time assessment is made according to part diameter, geometry, material, and order volume. Share your project; we will offer a realistic, project-specific production plan.
Fasteners are often used in critical applications — the failure of a single part risks the entire assembly. That is why quality is not a single check at the end of production, but a discipline embedded in every stage of the process.
Every raw material entering production is accepted with a material certificate. Wrong or non-conforming material never enters production.
Samples are taken at regular intervals throughout production; dimensional and visual checks are performed. If a deviation is detected, the line is stopped and corrected.
Parts pass through dimensional measurement and, when required, hardness / strength tests. The tolerances on the customer technical drawing are the reference.
Production is checked against the customer-approved specification and shipped. For customers who request it, we provide quality and dimensional reports, and batch-based traceability records when needed.
ANG FAST is a manufacturer known for precision engineering and high-quality fastening solutions. We meet the diverse needs of industries, prioritizing reliability and excellence in every product.

Choosing a fastener supplier is a long-term relationship of trust. At ANG FAST we build this relationship on four core principles.
Your technical drawings, samples, and project information are protected as trade secrets. We never share a customer's design or order with any other party — which is also why we do not openly publish our customer list. The care we show for you, we show for every customer.
We don't say "yes" to a lead time or specification we cannot meet. We speak realistically at the quotation stage, and deliver the work we accept at the promised quality and time.
We don't just take orders. We evaluate the manufacturability of your design and propose alternatives when needed. Our team is with you from the first meeting to mass production.
If there is a delay or a technical issue in production, we inform you in time. Predictability, not surprises, is essential.
ANG FAST is a growing manufacturing company. From the production line to sales and marketing, from office management to engineering — we are looking for teammates who do their job well and are eager to learn. Even if you don't see an open position, leave your application; we'll reach out when a suitable role opens.

Answers to the questions we hear most about production, materials, delivery, and ordering. If you don't find what you need, write to us.
Depending on part diameter, geometric complexity, and production method, our minimum order quantity is generally 25,000 pieces. Due to production and tooling costs, we can't accommodate very small batches below this. For larger diameters or highly custom geometries this minimum may vary — share your project details and we'll evaluate it specifically.
Low-carbon steel (1006, 1008, 1010), medium-carbon steel (1018, 1022, 1038), stainless steel (304, 316, 316L), brass (CuZn37), copper (Cu-ETP), and aluminum alloys (5052, 6061). Certified materials are sourced for defense-grade applications.
Yes. After technical drawing approval, 5-7 business days with existing tooling, 3-4 weeks if new tooling is needed. Samples come with dimensional report (CMM), hardness test, and tensile strength reports when required.
Surface treatments outside cold forging (zinc plating, hot-dip galvanizing, black oxide, Geomet, Dacromet, nickel plating) are done through our trusted partners. Parts can be delivered coated or uncoated per customer request.
Yes. We produce to common rivet standards (DIN 660, 661, 7337, 9021) and ISO norms (13918, 15983, 16585). Our core business is also customer-specific norm production based on company drawings.
In cold forging, metal is formed at room temperature inside a die — no material waste, with grain structure aligned to geometry yielding 20-30% higher strength. Machining (CNC turn/mill) removes material from raw bar; flexible at low volumes but waste and time costs rise at high volumes. See our detailed comparison section.
Yes. We export to Europe, Middle East, North Africa, and recently Latin America. Shipping terms (EXW, FOB, CIF, DAP) are determined per customer. We handle export documentation (ATR, EUR.1, certificate of origin).
For defense projects we work with material traceability, certified steel sourcing, and production reports. For specific confidentiality or technical requirements please reach us via the contact form.
