Description
1241613 NUT HEX M3 STAINLESS STEEL A4 — BOLTON SKU 58904.
About the 1241613 Fastener
Bossard part number 1241613 is an M3 hexagon nut supplied under the Bossard BN 629 family of standard hex nuts with a height of approximately 0.8d. It has the standard M3 coarse pitch of 0.5 mm and a width across flats of 5.5 mm, matching common M3 assembly tooling. The nut is manufactured from A4 austenitic stainless steel, the acid-resistant marine-grade fastener alloy, which offers higher corrosion resistance than the general-purpose A2 grade and is preferred where assemblies are exposed to moisture, salt atmospheres or chemically aggressive environments. As a standard coded fastener it pairs with A4 screws and washers of the same thread size to keep galvanic compatibility across the joint. Full material certification and batch traceability can be requested with the quotation where the application requires it.
