Countersunk-Washers-Detail Stamping is used at Engineering Hardware to make custom washers, retaining rings, panel latches & catches to a customer drawing. Cutting and forming sheet metal between a punch and a die, usually in one press stroke per part. The minimum order is 2,000–5,000 pieces and samples follow within 7 days of the drawing being approved. Cutting and forming sheet metal between a punch and a die, usually in one press stroke per part. Everything flat and thin in a fastener catalog comes from here: washers, retaining rings, spring clips, tab washers, panel clips, shims. A progressive die carries the strip through several stations so that blanking, forming and piercing all happen in one pass, which is why stamped parts are measured in fractions of a cent at volume. The die is the whole investment, and it is why stamping has a real minimum quantity. ## What Stamping is the right choice for - Flat and formed sheet parts at volume - Washers, clips, retaining rings, spring steel parts - Consistent parts at very low unit cost ## Where it is the wrong choice - Die cost has to be amortised — the wrong process for small runs - Thickness is limited by press capacity - Cut edges carry a burr that may need removing ## Parts produced this way - [Custom Washer](https://engineeringhardware.com/custom/washers/) — [56 standard parts in the catalog](https://engineeringhardware.com/fasteners/washers/) - [Custom Retaining Ring](https://engineeringhardware.com/custom/rings/) — [9 standard parts in the catalog](https://engineeringhardware.com/fasteners/rings/) - [Custom Panel Latch](https://engineeringhardware.com/custom/latches/) — [7 standard parts in the catalog](https://engineeringhardware.com/fasteners/latches/) - [Custom Support & Bracket](https://engineeringhardware.com/custom/supports/) — [14 standard parts in the catalog](https://engineeringhardware.com/fasteners/supports/) ## Usually combined with Stamping is rarely the only operation on a part. On most jobs it sits in a sequence with: - [Punching](https://engineeringhardware.com/custom/punching/) - [Etching](https://engineeringhardware.com/custom/etching/) ## Order terms - **Minimum order:** 2,000–5,000 pieces. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed. - **Samples:** Within 7 days of drawing approval. - **Drawing:** Preferred, but not required — a sample, photographs or a sketch is enough to start. ## What a quotation needs Nine things, and a drawing settles most of them at once. Where a field is unknown, say so — an assumption stated is better than a blank, and several of these can be recommended rather than specified. - **Drawing:** A 2D drawing (PDF or DWG) or a 3D model settles almost every other question on this list at once. - **Dimensions:** Diameter, length, head size and any features — enough to know what is being made. - **Tolerance:** Tolerance is the single biggest cost driver. Tell us which dimensions are critical and which are not — holding everything tight costs money on features nobody measures. - **Material:** Carbon steel, alloy steel, stainless, brass, aluminium, titanium — or the application, and we will suggest one. - **Strength grade:** Property class to ISO 898-1 (8.8, 10.9, 12.9) or stainless class to ISO 3506 (A2-70, A4-80). This decides the material and the heat treatment together. - **Thread standard:** Metric coarse, metric fine, UNC, UNF, BSW or a pipe thread — and the tolerance class if it is specified. - **Surface finish:** Zinc, hot-dip galvanised, black oxide, Dacromet, Geomet, nickel, passivation, or plain. Salt-spray hours if you have a requirement. - **Quantity:** Annual volume and first-order quantity. Volume changes which process is the right one, so it changes the price more than most buyers expect. - **Application & environment:** What the part holds together, and what it has to survive — temperature, vibration, chemicals, salt. This is what lets us catch a specification that will not work before it is made. ## Draw it here No CAD, no account, nothing to install. Draw the part in your browser, generate a real ISO metric thread from M1 to M100 with the end treatment it needs, dimension it, and export a PDF or a DXF to attach below. Sheets run to two metres for long studs and threaded rod. Open the drawing builder ## Questions ### What is the minimum order quantity for a custom part? Between 2,000 and 5,000 pieces for most parts. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed. ### How long does a sample take? Within 7 days once the drawing has been approved. The drawing stage comes first, and for a part being reverse-engineered from a sample it is where most of the time goes. ### Can you make a part without a drawing? Yes. A physical sample, photographs against a scale, or a dimensioned sketch are all workable starting points. A drawing is produced from whichever of those you have and sent back for approval before anything is made. ### When is Stamping not the right process? Die cost has to be amortised — the wrong process for small runs. Thickness is limited by press capacity. Cut edges carry a burr that may need removing. ### Which fasteners are made by stamping? In this catalog: washer, retaining ring, panel latch, support & bracket. Whether it is the right process for a particular part depends on the drawing and the quantity. ## Parts of this kind we already make Showing 36 of 44 Aluminium-Flat-Sealing-Washers Bearing Lock Washers Belleville Washers Bonded Sealing Washers category-washers Conical Spring Washers Countersunk Washers Cross-Bracing—Hillside-Washers Cup Washers Cup-Finishing-Washers-Detail din-6319g-conical-seat-washer din-6340-heavy-duty-clamping-washer E-Clip-Retaining-Washers EPDM Washers External-Tooth Lock Washers Extra-Thick-Heavy-Duty-Flat-Washers Fender Washers — DIN 9021 Finishing Washers Flat Plain Washer — GB – T 95 – ISO 7091 (Series 079) — GB – T 95 – ISO 7091 Flat Plain Washer (GB – T 95) — GB – T 97.1 – ISO 7089 (Series 086) — GB – T 97.1 – ISO 7089 Flat Washers — ISO 7089 ／ ISO 7093 Flat Washers — ISO 7089 ／ ISO 7093 Applications1 Flat Washers — ISO 7089 ／ ISO 7093 Detail General Flat Washer — GB – T 97.1 – ISO 7089 (Series 087) — GB – T 97.1 – ISO 7089 General Flat Washer — GB – T 97.2 – ISO 7090 (Series 088) — GB – T 97.2 – ISO 7090 Hex-Washer-Flange-Self-Drilling-Screws Insulating Washers Internal-Tooth Lock Washers iso-7092-flat-washer-small-series iso-7094-extra-large-flat-washer iso-8738-flat-washer-for-clevis-pins Leveling Washers Micro-Spring-Lock-Washers Neoprene Washers Nylon Washers Plain Washer — GB – T 858 (Series 071) — GB – T 858 These are catalog parts, shown to say what the tooling already covers.
