Our DIN Standard Brass Fasteners Process
DIN Drawing Review
Each product is manufactured against the exact DIN drawing — head dimensions, thread form, pitch, shank diameter all specified.
Raw Material to DIN Grade
Material alloy selection follows DIN material number specifications — e.g. DIN 17660/17672 for brass bar stock.
CNC Machining to DIN Tolerance
±0.01mm CNC machining ensures every critical dimension stays within DIN tolerance bands.
Thread Rolling to DIN Pitch
Thread rolling produces DIN-correct pitch, crest, and root form. Verified with DIN-calibrated Go/No-Go gauges.
DIN Compliance Report
Dimensional inspection report issued confirming compliance with the applicable DIN standard for each batch.

Why DIN Standards Matter for European Buyers
DIN standards are the backbone of European manufacturing procurement. When a German, French, or Italian engineer specifies 'DIN 933 M8 brass bolt', they expect exact head dimensions, thread pitch, and material grade. RKIC Group manufactures to these exact DIN specifications — not approximations — ensuring your fasteners fit first time every time.
Key DIN Standards We Manufacture To
Our most commonly requested DIN standards include DIN 933 (hex bolts full thread), DIN 931 (hex bolts part thread), DIN 934 (hex nuts), DIN 985 (nylon insert lock nuts), DIN 125 (flat washers), DIN 127 (spring washers), DIN 912 (socket head cap screws), DIN 603 (carriage bolts), and DIN 975/976 (threaded rods).
DIN vs ISO — What's the Difference?
Most DIN standards for fasteners have been harmonised with ISO standards — for example DIN 933 and ISO 4017 are technically equivalent for most dimensions. RKIC Group can supply products marked to either standard. Where DIN and ISO differ in a specific dimension, we manufacture to whichever standard is specified.
Export Documentation for DIN Fasteners
Every DIN fastener shipment includes a dimensional inspection report with DIN reference numbers, material test report, certificate of origin, and commercial invoice with HS tariff codes. EUR1 movement certificates for EU preferential duty are available on request.
