Description
Overview:
Hex Socket Head Cap Screws, Grade 12.9, M10 x 20 (pack of 10) are high-strength metric fasteners for secure joints in construction plant, industrial machinery, garden equipment, fixtures, and assemblies. Made from high-tensile steel to strength class 12.9 with a chemical black (black oxide) finish, they provide reliable clamping where space is tight and a cylindrical cap head is preferred. The hex socket drive allows accurate torque application with a standard Allen key for consistent, repeatable tightening. Length is 20 mm measured under the head; nominal thread diameter is 10 mm for M10 mating threads. Supplied as a matched set for uniform fit across multiple fixing points. Manufacturer Part Number (MPN): 903 0303. Suitable for use in tapped holes or with matching M10 nuts and washers in heavy-duty assemblies.
Key Features:
- Grade 12.9 steel for very high tensile and clamping strength in demanding assemblies
- M10 x 20 mm size, ideal where short grip length and compact head clearance are required
- Chemical black finish provides mild corrosion resistance and a low-glare appearance
- Hex socket head enables precise torque with standard Allen keys and reduces tool slip
- Cylindrical cap head fits recessed and confined locations better than hex bolts
- Consistent, accurate threads for smooth start and reliable engagement in tapped holes
- Pack of 10 matched screws for multi-bolt joints and maintenance spares
- Suitable for use with M10 nuts, spring or flat washers, and threadlocker as required
- Clean, burr-free chamfered ends aid quick alignment and faster assembly
- Durable construction supports repeated servicing when used within recommended torque
Typical Applications:
Securing gearboxes, motors, pumps, guards, brackets, and couplings; assembling jigs and fixtures; mounting engine and transmission components on plant and garden machinery; clamping bearing housings and slide rails; repairing frames and covers; general machine building and maintenance where a strong, compact, socket-driven fastener is preferred.
