Description
Overview:
These Hex Socket Head Cap Screws are high-strength fasteners for precise, load‐bearing assemblies. Size M6 x 45 mm (approx. 0.24 in x 1.77 in), they are manufactured to Grade 12.9 for exceptional tensile performance in demanding service. The screws are made from high‐tensile alloy steel with a chemical black finish that offers mild corrosion resistance and a low‐glare appearance. Designed for use with a hex key (Allen key), they suit tight access areas where a spanner head will not fit. Ideal for machinery assembly, construction and garden equipment, industrial plant, fixtures, and precision tooling, they provide reliable clamping where strength and accuracy are essential. Supplied in a pack of 10 for maintenance, repairs, or batch builds where consistent hardware is required.
Key Features:
- Grade 12.9 high-tensile steel for critical, high-load joints
- M6 diameter (6 mm / approx. 0.24 in) for common metric assemblies
- 45 mm length (approx. 1.77 in) for medium-depth clamping
- Hex socket head for secure drive and confined-space access
- Chemical black finish for mild corrosion resistance and clean appearance
- Accurate threads for smooth installation and consistent preload
- Works with standard hex keys and torque tools for repeatability
- Cylindrical cap head gives strong wrench engagement and reduced cam-out
- Suitable for vibration-prone applications when used with appropriate locking methods
- Pack of 10 to cover multiple fastenings or spares management
Typical Applications:
Commonly used in machine frames, motor and gearbox mounts, pump and compressor covers, guarding, tool fixtures, jigs, agricultural and garden machinery, and construction equipment. Suitable for repairs, upgrades, and new builds where a compact, high-strength fastener is needed. Provides dependable clamping in steel, aluminium, and engineered plastics when paired with correct washers or inserts.
Also known as:
Allen bolts, Allen cap screws, socket cap screws, SHCS, cap head bolts, internal hex cap screws, socket head bolts. Frequently used as metric cap screws in engineering drawings and maintenance manuals.
