Value Collection 44638 Hex Head Cap Screw M20 X 2.50 X 80 Mm

Product Description

The Value Collection 44638 is a metric hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 10.9 steel with a zinc-plated finish, this fastener delivers reliable clamping force and corrosion resistance in demanding environments. The screw features a partially threaded shank conforming to DIN 931 standards, an M20 x 2.50 thread size, and an 80 mm length under the head. It is installed using a 30 mm hex key or wrench. Sold in a package quantity of 10 units per order.

This fastener is suited for metric bolted connections in manufacturing, fabrication, heavy equipment maintenance, and general industrial assembly. The Grade 10.9 strength classification makes it appropriate for high-load structural joints where a full-strength metric cap screw is required. The partially threaded shank is standard for applications where a bearing surface or grip length is needed between mating components. Licensed mechanics, millwrights, maintenance technicians, and fabricators are the primary installers of this fastener type.

Key Features

• Grade 10.9 steel construction for high tensile and proof load ratings in demanding assemblies
• Zinc-plated finish provides baseline corrosion protection in standard service environments
• Partially threaded shank per DIN 931 allows a defined grip length between clamped surfaces
• M20 x 2.50 metric thread for compatibility with standard metric nuts and tapped holes
• 30 mm hex drive accepts standard metric wrenches and impact sockets
• Packaged in quantities of 10 to support job-lot purchasing

Compatibility

Designed as a DIN 931 metric hex head cap screw for use with M20 x 2.50 metric nuts and tapped components in standard metric bolted assemblies.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using a properly sized 30 mm wrench or impact socket. Always ensure mating threads and seating surfaces are clean and free of debris before assembly. Follow applicable engineering specifications or equipment service manuals for torque requirements specific to the joint design. Do not re-use fasteners in critical structural or safety applications unless the original equipment documentation permits it.
