Description
Overview:
These Hex Socket Head Cap Screws are high-strength fasteners for demanding assemblies in construction and garden machinery. Size M5 x 30 (5 mm diameter x 30 mm length), supplied in a pack of 10, they are manufactured from Grade 12.9 high-tensile steel for excellent clamping force and resistance to shear in high-stress joints. The chemical black (black oxide) finish provides added corrosion protection and a low-glare appearance. A cylindrical cap head with an internal hex drive allows positive engagement with standard hex keys and bit sockets, helping prevent cam-out and rounding. Suitable for repairs, upgrades, and new builds on equipment such as mowers, compactors, pressure washers, generators, and general workshop fixtures where reliable, repeatable fastening is essential.
