Value Collection 643237PR M20 X 2.50 X 75 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643237PR is a metric hex head cap screw engineered for general-purpose industrial fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener meets DIN 933 and ISO 4017 standards. The M20 x 2.50 thread profile runs the full 75 mm length under the head, providing maximum thread engagement in through-hole assemblies. A 30 mm hex drive size accommodates standard metric wrenches and sockets. At 0.505 pounds per unit, it offers the structural integrity expected of mid-strength metric fasteners used in machinery, structural steel connections, and heavy equipment maintenance.

This fastener is suited for industrial, commercial, and trade applications requiring a fully threaded M20 metric screw. Typical installations include steel fabrication, equipment assembly, mechanical maintenance, and structural connections where a DIN 933 or ISO 4017 compliant fastener is specified. The bright uncoated finish is appropriate for indoor or controlled environments where corrosion resistance is not a primary requirement. Licensed tradespeople and maintenance technicians working with metric hardware will find this screw compatible with standard metric tooling.

Key Features

• M20 x 2.50 thread size with full 75 mm threaded length under head
• Grade 8.8 steel construction for reliable mid-high tensile strength
• Meets DIN 933 and ISO 4017 standards for dimensional consistency
• 30 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no coating to interfere with thread fit
• Fully threaded shank maximizes thread engagement in through-hole applications

Compatibility

Designed as a DIN 933 and ISO 4017 compliant fully threaded hex head cap screw for use in any application specifying an M20 x 2.50 metric fastener.

Installation Notes

Installation should be performed by qualified tradespeople or maintenance technicians using calibrated metric torque equipment appropriate for Grade 8.8 fasteners. Always verify thread engagement depth and mating thread condition before assembly. Apply fasteners to clean, dry threads unless a specific lubricant or thread-locking compound is called out in the engineering specification. Follow applicable industry or equipment manufacturer torque guidelines for M20 Grade 8.8 hardware.
