Description
Overview:
The Hex Socket Head Cap Screw M20 x 75 is a high‐tensile fastener for secure, space‐saving clamping in machinery and equipment. Made from Grade 12.9 alloy steel, it provides very high tensile strength and dependable performance in demanding assemblies. The chemical black finish helps resist wear and light corrosion while giving a clean, low‐glare appearance. With a hex socket drive, it is tightened using a standard hex key or bit, allowing precise torque and easy access in tight areas. Size M20 x 75 mm refers to a 20 mm nominal thread diameter with 75 mm length measured under the head. Supplied individually, it suits repairs, maintenance, and builds across construction plant, agricultural and garden machinery, workshop fixtures, and industrial equipment where strength and reliability are critical.
Key Features:
- Grade 12.9 high‐tensile steel for maximum clamping strength and fatigue resistance
- M20 x 75 mm sizing for heavy‐duty joints and structural connections
- Hex socket head for positive drive and reduced risk of tool slip
- Chemical black finish for improved wear resistance and low‐reflective appearance
- Compact cap head profile for use where clearance is limited
- Precise machining for consistent fit and alignment in threaded holes
- Compatible with standard hex keys and driver bits for easy installation
- Suitable for use with threadlockers and hardened washers where required
- Sold individually to match exact repair or build quantities
- Commonly available alternatives include zinc‐plated or stainless variants if corrosion exposure is higher
Typical Applications:
Used for assembling and repairing construction and industrial equipment, plant and machinery, power transmission housings, pump and motor mounts, fixtures, guarding, and tooling. Ideal wherever high tensile strength and a neat, compact head are needed, such as engine and gearbox covers, brackets, frames, and precision jigs.
