Description
Overview:
The Hex Socket Head Cap Screw M10 x 30 is a high‐strength fastener for demanding assemblies in construction, agricultural, garden, and general industrial machinery. Made from Grade 12.9 steel with a chemical black finish, it offers very high tensile strength with good wear resistance and dependable performance under vibration and shock. The internal hex drive allows firm tool engagement where spanner clearance is limited, helping prevent tool slip and head damage. A standard right‐hand metric thread makes it straightforward to replace worn or missing fixings in existing equipment. Supplied in a pack of 10, it is well suited to workshop maintenance, repairs, and small production runs where consistent quality and reliable clamping are essential.
Key Features:
- Grade 12.9 high tensile steel for maximum strength and durability
- Right‐hand metric thread for straightforward replacement and compatibility
- Hex socket head for secure drive engagement and reduced cam‐out
- Chemical black finish to help resist corrosion and reduce glare
- M10 x 30 size suitable for a wide range of machinery assemblies
- Compact head profile works well in counterbores and tight spaces
- Accurate manufacturing for consistent fit and reliable preload
- Supplied as a pack of 10 for convenient workshop stock control
- Compatible with standard hex (Allen) keys and torque tools
- Ideal for applications subject to vibration when correct torque is applied
Typical Applications:
Commonly used for assembling and repairing machinery frames, brackets, guards, covers, gearboxes, motor mounts, pump housings, and fixtures. Suitable for plant and site equipment, workshop jigs, agricultural implements, and garden machinery where strong, compact fixings are needed. Works in both tapped holes and through‐holes (with a matching M10 nut and washer) when specified torque and thread engagement are observed.
Also known as:
Allen bolt, Allen cap screw, socket head cap screw (SHCS), hex key bolt, internal hex bolt, high tensile cap screw, metric socket cap, socket screw, cap head screw, machine screw (cap head type). These terms are commonly used across engineering, maintenance, and fabrication when referring to this style of fastener.
