Value Collection 815234PS Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 815234PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It is manufactured from Grade 8.8 carbon steel with a zinc-plated finish that provides baseline corrosion resistance. The screw measures M20 x 2.50 in thread size with a 65 mm length under the head and features partial threading along the shank. A 30 mm hex drive size is required for installation. This fastener conforms to DIN 931 and ISO 4014 standards, making it a direct fit for metric-specification assemblies. Maintenance technicians, millwrights, and field service professionals working on industrial equipment, machinery frames, and structural hardware will find this screw appropriate for medium-to-high-strength bolted joint applications.

The 815234PS is suited for metric fastening tasks in manufacturing, equipment maintenance, and mechanical assembly environments. Its partial-thread shank design is appropriate for through-bolt and clearance-hole applications where a grip length must remain unthreaded. The Grade 8.8 rating places it in the medium-high strength category, handling loads that exceed the capacity of common Grade 4.8 or 5.8 hardware. It is sold individually and is appropriate for single-replacement jobs or low-volume assembly work.

Key Features

Compatibility

Designed as a DIN 931 and ISO 4014 compliant metric hex head cap screw for use in any application specifying an M20 x 2.50 partially threaded fastener in Grade 8.8 steel.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener specifications and torque requirements. Always verify that the mating threads, nut, or tapped hole are clean and undamaged before installation. Use a properly sized 30 mm hex wrench or socket to avoid rounding the head. Do not exceed the torque specification for Grade 8.8 fasteners as published in the relevant engineering standard for the application.
