Description
Overview:
These Hex Socket Head Cap Screws (Grade 12.9) are high‐tensile alloy steel fasteners for secure assembly in demanding machinery and equipment. The cylindrical cap head with an internal hex drive allows high torque using a standard hex key while keeping a tidy, compact profile. Finished in chemical black (black oxide), they offer added surface protection against corrosion. Size is M3 × 10, meaning a 3 mm thread diameter and 10 mm length (approximately 0.12 in × 0.39 in). Suitable for use in threaded holes or with matching M3 nuts, they are ideal for plant, automotive, and industrial applications where strength, accuracy, and repeatable clamping are required. Supplied as a pack of 10 for maintenance, repairs, prototypes, and small production runs.
Key Features:
- Grade 12.9 high‐tensile alloy steel for strong, reliable clamping in high‐load assemblies
- Chemical black (black oxide) finish for added corrosion resistance and a low‐glare surface
- Metric size M3 × 10 with imperial reference approx. 0.12 in × 0.39 in (3 mm × 10 mm)
- Internal hex socket head for positive drive and reduced risk of tool slip
- Precision threads for consistent fit in tapped holes and with M3 nuts
- Compact cap head suits counterbored holes and confined spaces
- Pack of 10 screws to cover typical service, repair, and build tasks
- Simple to install and remove using a standard hex key or bit socket
Typical Applications:
General machinery assembly and repair, brackets and guards, fixtures and jigs, motor and gearbox mounts, small housings, covers, and clamping plates. Commonly used on construction equipment, workshop machines, conveyors, pumps, agricultural and garden machinery, and automotive components where a strong, compact fastener is needed.
Also known as:
Allen bolts, socket head cap bolts, caphead screws, socket cap bolts, SHCS, internal hex cap screws, cap head bolts, socket screws.
