Description
Overview:
These Hex Socket Head Cap Screws are high-strength M6 fasteners with a 40 mm under‐head length, supplied in a pack of 10. Made from Grade 12.9 alloy steel, they provide excellent tensile strength for critical joints in machinery and equipment. The chemical black finish offers enhanced corrosion resistance and a low‐glare appearance, suitable for workshop and site use. The internal hex drive allows reliable torque transfer and easy access in tight spaces compared with standard hex bolts. Ideal for construction machinery, garden equipment, machine tools, pumps, and gearboxes, they provide a secure, repeatable clamp in tapped holes or when used with matching M6 nuts and washers. A practical choice for repairs, maintenance, and precision engineering assemblies where consistent, high‐integrity fastening is required.
Key Features:
- Size: M6 thread, 40 mm under‐head length (metric)
- Pack of 10 for convenient stocking and multi‐bolt assemblies
- Grade 12.9 alloy steel for very high tensile strength and durability
- Chemical black (black oxide) finish for enhanced corrosion resistance
- Hex socket head allows high torque transfer and neat, compact installation
- Typically uses a 5 mm hex key for fitting and removal
- Consistent head and thread geometry for accurate, repeatable clamping
- Suitable for use in tapped holes or with M6 nuts and appropriate washers
- Reliable in high‐vibration environments when installed to the correct torque
- Clean, professional appearance for exposed assemblies
Typical Applications:
Used across plant and machinery assembly, guards and covers, brackets, jigs and fixtures, motor and pump mounts, gearboxes, and frame joints. Common in fabrication, maintenance, and repair of construction equipment, compressors, generators, and garden machinery where a compact, high‐strength fastener is needed in confined spaces.
