Description
Overview:
These Hex Socket Head Cap Screws, Grade 12.9, Size: M5 x 35, are high-strength fasteners for demanding assembly and maintenance tasks on construction and garden machinery, tools, and general mechanical projects. Made from high-tensile alloy steel, they deliver reliable clamping force in compact assemblies. The chemical black finish offers enhanced corrosion resistance and a low-glare appearance. Each screw has an internal hex drive for positive engagement with a hex key or bit, making installation straightforward in tight or recessed locations. With a 35 mm under-head length and M5 machine thread, they suit brackets, guards, housings, engine covers, and fixtures where accuracy and strength matter. Supplied in a practical pack of 10 for workshop replenishment. Manufacturer Part Number (MPN): 903 0283.

Typical Applications:
Used for assembling and repairing machinery frames, motor mounts, gearboxes, guards, brackets, and tool fixtures. Common across industrial equipment, generators, pumps, compactors, and garden machinery such as mowers and chippers. Also suitable for jigs, robotics, and precision assemblies where a strong, tidy fastener is preferred and access for a spanner is limited.
