Description
Overview:
These Hex Socket Head Cap Screws are high-tensile fasteners for demanding assemblies in construction, plant, and garden machinery. Made from Grade 12.9 alloy steel with a chemical black (black oxide) finish, they offer strong clamping force and dependable service in heavy-duty use. The internal hex drive makes them easy to fit with a standard Allen key or hex bit. Size M8 x 55 mm suits many brackets, guards, housings, and structural joints on equipment such as generators and compactors. The cylindrical cap head allows use in counterbored holes and tight spaces where spanner clearance is limited. Supplied in a Pack of 10 for straightforward maintenance and replacements. Part number: 903 0299 100PK. This listing is for M8 x 55; other sizes may be available across the same range.
