Distribution-grade batches with RoHS/REACH declarations. Application at a glance ### Typical component families | Special screws from drawing | Alloy steel, stainless, forged | Plastic screws | PA66, POM, turned/forged | Pins, dowels, connector parts | 42CrMo4, C17200, precision ### Typical supply parameters | Batch range | 10–50,000 pcs, tiered pricing | Documentation | RoHS/REACH, dimension reports | Tolerance scheme | DIN ISO 2768-mK / drawing fits ## Industry scenario: part-number procurement with certificate expectations Fastener distributors and hardware traders procure differently from OEMs: orders arrive by part number, certificates (RoHS, REACH) are requested with the first quotation, and tiered pricing across quantity steps decides the business. Non-standard parts — special screws, plastic screws, precision pins — are sourced from drawings when no catalog part fits. The winning supplier profile combines cold forging and thread rolling for volume screws, turning for precision pins and connector components, and a documentation process that delivers RoHS/REACH declarations and dimension reports without chasing. ## Typical component families and processes | Component (DE / EN) | Typical material | Process | Typical batch | Sonderschrauben (special screws from drawing) | alloy steel, stainless steel | cold forging + thread rolling | 10,000+ pcs/month | Kunststoff-Schrauben (plastic screws) | PA66, POM | turning / cold forging | 5,000+ pcs | Bolzen / Zylinderstifte / Passstifte (pins, dowels) | 42CrMo4, stainless steel | cold forging or turning + grinding | 1,000–50,000 pcs | Steckverbinder-Komponenten (connector components) | C17200 beryllium copper, brass | Swiss-type turning | tiered 10–1,000 pcs Tiered pricing across quantity steps (e.g. 10/50/500/1,000) matches distribution procurement patterns. ## Workflow: drawing, sample approval and recurring series The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Batch sizes follow the table above — from single spare parts to tens of thousands of pieces per order, depending on the component family. For repeat orders, tooling, program revisions and inspection records are kept on file, so call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, packaging changes — are handled as controlled changes against the same records. ## Quality and documentation DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Surface treatment, cleanliness and packaging requirements are confirmed per drawing. ## FAQ Can you quote from a catalog part number?For non-standard parts, yes — from drawing or sample. Standard catalog fasteners are better sourced from fastener wholesalers; our strength is the drawing-based special part. Are RoHS and REACH declarations available?Yes, issued with the delivery for the supplied materials and surface finishes. Do you support tiered pricing across quantity steps?Yes — pricing is structured across the typical distribution quantity ladder, e.g. 10/50/500/1,000 pieces. Can you make plastic screws in PA66 or POM?Yes, by turning and cold forging, in distribution-grade batches from 5,000 pieces. ### Related Materials · Related Services · Related Case Studies [Related Materials: Steel ](https://www.sinbo-machining.com/products/materials/steel/)[· Plastic ](https://www.sinbo-machining.com/products/materials/plastic/)[Related Services: Cold Heading ](https://www.sinbo-machining.com/services/cold-heading/)[Related Case Studies: Kr Special Fasteners ](https://www.sinbo-machining.com/case/kr-special-fasteners/)[· Jp Fasteners ](https://www.sinbo-machining.com/case/jp-fasteners/)This page describes a representative application scenario for the fastener distribution and hardware trade industry, compiled from typical requirements of this vertical.
