Value Collection 815265PR Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 815265PR is a metric hex head cap screw engineered for industrial and mechanical fastening applications. Built to Grade 8.8 steel with a zinc-plated finish, this fastener delivers reliable tensile strength and corrosion resistance. The shank is partially threaded with an M20 x 2.50 thread form and a 170 mm length under head. A 30 mm hex drive size makes it compatible with standard metric tooling. This screw conforms to DIN 931 and ISO 4014 dimensional standards and is installed by millwrights, maintenance mechanics, and structural assembly technicians across a wide range of fabrication and equipment environments.

This fastener is suited for medium-to-heavy mechanical assemblies where a partially threaded grip section is required to align mating components or carry shear load. Common applications include equipment frames, structural steel connections, machine bases, and industrial fixtures. The zinc plating provides a base level of protection against surface oxidation in dry to mildly humid environments. Grade 8.8 tensile strength makes it appropriate for general-purpose structural fastening where high-strength alloy grades are not required.

Key Features

• M20 x 2.50 metric thread form, 170 mm length under head
• Grade 8.8 steel construction for reliable tensile and yield strength
• Zinc-plated finish for basic corrosion resistance
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 30 mm hex drive size for use with standard metric wrenches and sockets

Compatibility

Designed as an OEM-style replacement or direct-use metric fastener for machinery, structural steel assemblies, and equipment frames requiring a partially threaded M20 hex head cap screw to DIN 931 or ISO 4014 specifications.

Installation Notes

Installation is performed with a 30 mm metric wrench or socket. Verify thread engagement depth and mating material before torquing to avoid cross-threading or stripping. Follow applicable torque specifications from the equipment manufacturer or relevant fastener engineering standards for Grade 8.8 metric hardware. Inspect the zinc-plated coating for damage before installation, as compromised plating in corrosive environments may require additional anti-corrosion measures.
