Value Collection 532310BR M20x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532310BR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, making it one of the highest-strength grades available for socket cap screws. The M20 x 2.50 thread size with a 110 mm length under head provides substantial clamping force in heavy-duty bolted joints. Installation requires a hex socket driver or hex key of the appropriate size. This screw is partially threaded, which is standard practice for bearing-surface and shear-load applications.

This screw is suited for use in machinery, heavy equipment, tooling fixtures, die sets, and structural steel assemblies where high clamping force and a low-profile head are required. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision equipment environments. Sold in a minimum order quantity of 10 pieces per order. This fastener is appropriate for use by mechanical assemblers, millwrights, tool and die makers, and maintenance technicians working to metric fastener specifications.

Key Features

• Material grade 12.9 alloy steel for maximum tensile and proof load strength
• Black oxide coating provides mild corrosion resistance and a low-glare finish
• Partially threaded shank supports shear and bearing loads in bolted joints
• Meets DIN 912 and ISO 898-1 fastener standards for dimensional and mechanical compliance
• M20 x 2.50 thread with 110 mm length under head for heavy-duty fastening depth
• Hex socket drive allows high torque application in confined spaces

Compatibility

Designed as a standard metric hex socket cap screw per DIN 912, compatible with M20 x 2.50 tapped holes in machinery, structural assemblies, and tooling fixtures requiring a grade 12.9 fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or assembler using a calibrated torque wrench and the correct hex socket bit for M20 socket cap screws. Ensure tapped hole depth and thread engagement meet minimum requirements per engineering specifications before final tightening. Clean and inspect the mating threads for damage or contamination prior to assembly. Do not use impact drivers without a torque-limiting attachment, as grade 12.9 fasteners are susceptible to hydrogen embrittlement and overtorque failure.
