Value Collection 644325PS Hex Cap Screw M24x3 150mm Grade 8.8

Product Description

The VALUE COLLECTION 644325PS is a metric hex head cap screw designed for medium-to-high-strength fastening applications in mechanical assemblies, structural connections, and industrial equipment. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this screw delivers a reliable tensile strength profile suited to demanding bolted joints. The partially threaded shank follows DIN 931 and ISO 4014 standards, which govern dimensional tolerances and thread form for metric hex bolts. With an M24 x 3.00 thread size and a 150 mm length under head, this fastener is sized for heavy-duty connections requiring a larger-diameter bolt. It is installed using a 36 mm hex wrench or socket.

This cap screw is used across a wide range of commercial, industrial, and trade applications including structural steel fabrication, heavy equipment assembly, pump and motor mounting, and general mechanical maintenance. The partial thread design provides a smooth shank section between the head bearing face and the threaded zone, which is appropriate when a grip length without thread engagement is needed through the clamped material. Maintenance technicians, millwrights, pipefitters, and general contractors commonly use fasteners of this specification when working to metric standards.

Key Features

• M24 x 3.00 thread form per DIN 931 and ISO 4014 dimensional standards
• 150 mm length under head with partial threading for controlled grip length
• Grade 8.8 steel construction for high-load bolted joint applications
• Bright uncoated finish — suitable for dry or protected environments
• 36 mm hex drive compatible with standard metric hex sockets and wrenches
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as an OEM-style or maintenance replacement hex head cap screw for any metric bolted assembly specifying an M24 x 3.00 partially threaded bolt at 150 mm under-head length per DIN 931 or ISO 4014.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or tradesperson familiar with metric fastener torque specifications for the application. Always verify the correct torque value from the equipment manufacturer's service documentation for Grade 8.8 fasteners at this diameter — do not estimate. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench; do not use impact tools without a verified torque audit step.
