Value Collection A996756 M20x2.50 Hex Socket Cap Screw 5pk

Product Description

The VALUE COLLECTION A996756 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at M20 x 2.50 with a 160 mm length under head, this screw is partially threaded and features a hex drive for use with a standard hex key or Allen wrench. Manufactured from alloy steel at material grade 12.9, it delivers exceptional tensile strength. A black oxide finish provides basic corrosion resistance and reduces light reflection in precision assemblies. Sold in a pack of 5.

This fastener is suited for heavy-duty mechanical assemblies, machine frames, dies, fixtures, jigs, and structural joints where a recessed drive and high clamping load are required. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for close-tolerance applications. Machinists, millwrights, maintenance technicians, and industrial assemblers are the primary installers. It meets DIN 912 and ISO 898-1 fastener standards.

Key Features

• M20 x 2.50 metric thread with 160 mm length under head
• Grade 12.9 alloy steel construction for high tensile and yield strength
• Partially threaded shank for shear-load bearing in close-tolerance bores
• Hex socket drive compatible with standard Allen keys and hex-drive bits
• Black oxide finish for reduced surface reflectivity and mild corrosion resistance
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for any M20 x 2.50 threaded hole application in industrial machinery, fabricated steel assemblies, and maintenance repair operations.

Installation Notes

Installation requires a hex key or hex-drive socket sized for an M20 socket cap screw. Always verify thread engagement depth and torque to the assembly specification for grade 12.9 fasteners per the applicable engineering standard. Inspect the mating threaded hole for proper class of fit before installation. Replace any fastener that shows signs of galling, corrosion, or deformation.
