Value Collection 532316BR M20 X 2.50 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532316BR is a metric hex socket cap screw designed for high-strength fastening applications. It features an M20 x 2.50 thread and a length under head of 140 mm (approximately 5.51 inches). Manufactured from alloy steel to material grade 12.9, it carries a black oxide finish that provides mild corrosion resistance and reduces light reflection. This fastener is partially threaded and driven with a hex key (Allen wrench). It conforms to DIN 912 and ISO 898-1 standards, making it suitable for precision mechanical assemblies requiring a reliable, high-load bolt.

This screw is used wherever a flush, recessed-drive fastener is needed in metal-to-metal assemblies. Common applications include machine frames, jigs and fixtures, tooling plates, industrial equipment, and structural mechanical joints. The M20 size is typical in medium-to-heavy fabrication work encountered in industrial maintenance, millwright work, and equipment manufacturing. The 12.9 material grade indicates a high-tensile fastener appropriate for joints under significant clamp load.

Key Features

• M20 x 2.50 metric thread for high-load fastening applications
• 140 mm length under head (approximately 5.51 inches), partially threaded
• Alloy steel construction at material grade 12.9 for maximum tensile strength
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Hex socket (Allen) drive allows torquing in recessed or confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M20 x 2.50 threaded bores in metal assemblies, machine frames, and industrial equipment per ISO 898-1 specifications.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or machinists using a calibrated torque wrench and the appropriate metric hex key or socket. Always verify the mating thread is clean and free of debris before installation. Grade 12.9 fasteners should not be substituted with lower-grade hardware in critical load-bearing joints. Follow applicable engineering specifications or equipment manufacturer guidelines for torque values on M20 grade 12.9 fasteners.
