Description
Overview:
These Hex Socket Head Cap Screws are high‐strength fasteners made from Grade 12.9 alloy steel with a chemical black (black oxide) finish for added surface protection. Size M8 x 16 means an 8 mm nominal thread diameter with 16 mm length under the head; the length also equals 0.63 inches (approximately 16 mm). The cylindrical socket head uses an internal hex drive for positive engagement with an Allen key, helping achieve reliable clamp loads in restricted spaces. Supplied in a pack of 10, they suit construction and garden machinery, metalwork jigs, power equipment, gearboxes, and precision assemblies where a compact, high‐tensile fixing is needed. Ideal for tradespeople and DIY users working on plant, workshop fixtures, or equipment repairs.
Key Features:
- Grade 12.9 alloy steel for very high tensile strength and dependable clamping
- Chemical black (black oxide) finish offers light corrosion resistance and a low‐glare appearance
- M8 x 16 mm length (0.63 in) for common machinery and fabrication tasks
- Socket (Allen) drive provides strong tool engagement and reduces cam‐out
- Compact cylindrical head suits recesses and tight clearances
- Precisely formed threads for consistent fit and repeatable torque
- Supplied in a pack of 10 for maintenance kits and small batch builds
- Compatible with standard metric Allen keys and torque tools
- Suitable for steel‐to‐steel joints and assemblies requiring high preload
- Reliable choice for repairs, retrofits, and new builds across workshops and site work
Typical Applications:
Commonly used in machinery frames, motor mounts, bearing housings, pulleys and guards, fabrication fixtures, jigs, and brackets. Well suited to construction equipment, garden machinery, compressors, pumps, gearboxes, and tool assemblies where strong, compact fixings are required and access is limited.
Also known as:
