Value Collection 460238PR M20 Hex Cap Screw 80mm Grade 10.9

Product Description

The VALUE COLLECTION 460238PR is a metric hex head cap screw intended for heavy-duty fastening applications where high tensile strength and corrosion resistance are required. Built to DIN 931 standards, this fastener features an M20 x 2.50 thread profile and measures 80 mm in length under the head. The Grade 10.9 steel construction delivers a high tensile strength rating suitable for demanding mechanical and structural assemblies. A zinc-plated finish provides a baseline layer of corrosion protection. This screw is partially threaded, with a 30 mm hex drive size for use with standard metric wrenches or sockets. Machinists, millwrights, and maintenance technicians are the typical installers.

This fastener is suited for use in metric-dimensioned mechanical assemblies across industrial, agricultural, and heavy equipment applications. The partially threaded shank is advantageous when clamping two components where thread engagement is needed only at the nut end, allowing the unthreaded shank to bear shear loads without thread deformation. It is commonly used in structural steel connections, machinery frames, and equipment mounting brackets that specify DIN 931 hardware.

Key Features

• M20 x 2.50 metric thread profile conforming to DIN 931 standard
• Grade 10.9 steel construction for high tensile and proof load strength
• Partially threaded shank to support shear load applications
• Zinc-plated finish for baseline corrosion protection
• 30 mm hex drive size compatible with standard metric wrenches and sockets
• 80 mm length under head for medium-depth clamping requirements

Compatibility

Designed as a DIN 931 compliant metric hex head cap screw suitable for standard M20 x 2.50 metric threaded applications in industrial and heavy equipment assemblies.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using a properly sized 30 mm metric wrench or socket. Always verify thread engagement depth and mating thread condition before torquing. Follow the applicable equipment manufacturer torque specifications for Grade 10.9 fasteners at this thread size. Ensure mating surfaces are clean and free of debris to achieve proper clamp load.
