Value Collection 643238PS Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 643238PS is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, structural connections, and equipment fabrication. It carries a Grade 8.8 steel classification, indicating a medium-high tensile strength suitable for demanding bolted joints. The fastener is fully threaded along its 80 mm length under head and features a 30 mm hex drive. It is supplied in a bright, uncoated finish and conforms to DIN 933 and ISO 4017 standards. Licensed tradespeople and experienced technicians handling metric fastener work will find this screw a straightforward, spec-compliant choice for a wide range of metal-to-metal applications.

This screw is appropriate for use in industrial machinery, HVAC equipment frames, pump and motor mounting, structural steel fabrication, and general mechanical assemblies requiring metric fasteners. Its full threading from tip to head makes it well suited for through-bolting applications where a nut is used on the opposite side, or for threading directly into tapped holes. Minimum order quantity is 5 pieces; each package contains 1 piece.

Key Features

• Grade 8.8 steel construction provides reliable tensile and yield strength for demanding bolted connections
• Fully threaded shaft along the entire 80 mm length under head for maximum thread engagement
• M20 x 2.50 thread size with 30 mm hex drive for standard metric tooling
• Bright uncoated finish — suitable for dry or controlled-environment installations
• Conforms to DIN 933 and ISO 4017 standards for dimensional and mechanical consistency
• UNSPSC Code 31161501 for procurement and inventory classification

Compatibility

Designed as an OEM-style metric fastener replacement or new-build component for any application requiring a fully threaded M20 x 2.50 hex head cap screw conforming to DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is performed by mechanics, millwrights, pipefitters, or HVAC technicians working with metric fastener systems. Use a properly sized 30 mm wrench or socket to drive the fastener to the torque value specified by the equipment manufacturer or applicable engineering standard. De-energize and lock out all equipment before accessing fastener locations on live machinery. Do not mix metric and imperial fasteners in the same joint, and always verify thread engagement depth meets the requirements of the assembly design.
