Value Collection 815241PS M20 Hex Cap Screw Grade 8 Zinc

Product Description

The VALUE COLLECTION 815241PS is a metric hex head cap screw designed for general-purpose industrial fastening applications requiring strength and corrosion resistance. Manufactured from Grade 8 steel with a zinc-plated finish, this screw delivers reliable clamping force in moderate-exposure environments. It features a partially threaded shank per DIN 931, with an M20 x 2.50 thread profile and a 90 mm length under head. The 30 mm hex drive size accommodates standard industrial wrenches. This fastener is suited for mechanical assembly, structural bracketing, and equipment maintenance work performed by millwrights, maintenance technicians, and general trades professionals.

This cap screw is used in metric fastening applications across industrial machinery, structural steel assemblies, and heavy equipment maintenance. Its partially threaded shank makes it appropriate where a smooth shank section is needed for shear loading or close-tolerance bores. The DIN 931 standard ensures dimensional consistency for replacement and repair work where original hardware must be matched to specification. Sold individually, it fits single-unit repair jobs as well as larger assembly tasks.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical trades. De-energize and lock out any equipment before replacing structural fasteners. Use a calibrated torque wrench appropriate for M20 fasteners and follow the equipment manufacturer's torque specifications for the assembly being serviced. Inspect mating threads for damage or contamination before installation.
