Value Collection 44644 Hex Head Cap Screw M20 X 2.50

Product Description

The Value Collection 44644 is a metric hex head cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from Grade 10.9 steel with a zinc-plated finish, this fastener delivers high tensile strength and basic corrosion resistance. The M20 x 2.50 thread profile runs partially threaded along a 120 mm length under head, conforming to DIN 931 and ISO 4014 standards. The 30 mm hex drive size accepts standard industrial hex wrenches and impact sockets. This fastener is suited for torque-critical connections where high-grade steel hardware is specified. Sold in a package quantity of 3.

This screw is appropriate for use in heavy-duty mechanical assemblies, equipment mounting, flanged connections, and structural bolted joints where metric fasteners and Grade 10.9 material requirements are called out in design specifications. Partial threading is standard for this length and size class, providing a bearing shank in the grip zone. Suitable for use in both OEM manufacturing environments and field maintenance applications across industrial trades.

Installation Notes

Installation is typically performed by millwrights, mechanical assemblers, or maintenance technicians using calibrated torque wrenches or torque-controlled impact tools sized for a 30 mm hex drive. Always consult the applicable engineering specification or fastener torque table for Grade 10.9 M20 fasteners before final tightening. De-energize and lock out equipment before removing or replacing structural fasteners. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.
