Fgruh M6 Hex Socket Head Cap Screws Kit 185pcs 12.9 Alloy Steel

Fgruh M6 Hex Socket Head Cap Screws Kit

This 185-piece M6 fastener kit supplies hex socket head cap bolts, matching nuts and washers for hobbyists and technicians working on 3D printers, RC models, CNC machinery or general DIY repairs. Every component is manufactured from 12.9 grade alloy steel with a black zinc finish that resists corrosion and leaves no oily residue on parts or hands.

Upgrading from mixed or lower-grade assortments

Builders replacing assorted mild-steel or ungraded hardware gain consistent 12.9 tensile strength and a controlled 1.0 mm thread pitch across eight lengths from 8 mm to 35 mm. The jump is worth it when repeated assembly cycles demand reliable clamp load and the organised case eliminates time lost searching for the correct size.

Capacity and headroom for M6 fastening

The kit comfortably handles routine M6 installations in metal, plastic and wood where a 12.9 bolt with matching nut and washer provides ample clamping force for structural joints and vibration-prone mounts. It runs out when a project requires sizes other than M6, thread pitches different from 1.0 mm, or corrosion resistance beyond what black zinc plating delivers in prolonged outdoor exposure.
