Description
Overview:
These Hex Socket Head Cap Screws are high‐tensile fasteners for demanding assembly work on machinery and equipment. Made from Grade 12.9 alloy steel with a chemical black (black oxide) finish, they offer excellent strength with added surface protection. The cylindrical socket cap head uses an internal hex drive for positive engagement and tidy, flush seating in counterbored holes. Size M8 x 20: thread diameter 8 mm (0.31 in) and length under head 20 mm (0.79 in). Supplied as a pack of 10, they are well suited to construction plant, industrial equipment, and garden machinery where reliable clamping force and consistent alignment are needed in high‐stress or vibrating assemblies.
Key Features:
- Grade 12.9 high‐tensile steel for strong clamp loads and dependable performance in high‐stress joints
- Chemical black (black oxide) finish for mild corrosion resistance and a low‐glare surface
- Hex socket head for secure drive and easy installation using standard metric hex keys/Allen bits
- Practical size M8 x 20: 8 mm diameter (0.31 in) and 20 mm length (0.79 in) for common machinery fixings
