Description
Overview:
These Hex Socket Head Cap Screws are high‐tensile fasteners made from heat‐treated alloy steel to Grade 12.9 for maximum strength in compact joints. Supplied in M10 x 100 size (10 mm diameter x 100 mm length, approx. 0.39 in x 3.94 in), they provide reliable clamp force where space is tight and access is via a hex key. The cylindrical socket head sits neatly in counterbored or recessed locations, helping achieve precise, repeatable assembly. A chemical black finish adds light corrosion resistance and a clean appearance for machinery, fixtures, and structural assemblies used indoors or outdoors. Ideal for construction equipment, plant, agricultural and garden machinery, workshop jigs, and precision engineering tasks where consistent performance and high preload are required. Supplied as a pack of 10. MPN: 903 0310.
Key Features:
- Grade 12.9 alloy steel for very high tensile strength and dependable clamping in demanding joints
- M10 x 100 (10 mm x 100 mm / approx. 0.39 in x 3.94 in) for common through-holes and tapped M10 threads
- Chemical black finish for enhanced surface protection and reduced glare in assembly environments
- Socket head design allows use in counterbored/recessed holes and close-clearance locations
- Precision-machined internal hex drive for positive engagement with standard metric hex keys/bit sockets
- Consistent thread and head geometry for smooth installation and accurate torque control
- Suitable for use with M10 nuts or directly into tapped steel or alloy components
- Pack of 10 for straightforward stocking, maintenance, and batch assembly tasks
- Works across construction plant, machinery frames, brackets, housings, guards, and fixtures
- Part of a wider range with multiple finishes and sizes available (e.g. zinc plated, stainless; M3 x 10 to M24 x 100)
Typical Applications:
High-strength fastening in machinery assembly, power transmission covers, engine and gearbox brackets, hydraulic and pneumatic equipment, fabrication jigs, machine guards, and garden or construction equipment repairs. Ideal where a compact head and a strong, repeatable clamp load are required, and installation is by hex key or hex bit with a torque wrench.
