Value Collection 42064 M8 X 1.25 55mm Hex Cap Screw Grade 8.8

Product Description

The Value Collection 42064 is a metric hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, it delivers reliable tensile strength and basic corrosion resistance in typical shop, equipment assembly, and maintenance environments. The M8 x 1.25 thread profile and 55 mm length under head make it a standard choice for medium-duty bolted joints. The partially threaded shank allows it to draw mating parts together cleanly without thread engagement along the full grip length. This fastener conforms to DIN 931 and ISO 4014 standards.

This screw is suited for use in machinery assembly, equipment fabrication, and structural connections where a metric fastener with controlled tensile properties is required. The Grade 8.8 rating indicates a minimum tensile strength appropriate for moderate-load bolted joints in steel and aluminum components. Typical installers include millwrights, maintenance mechanics, and fabricators working with metric-dimensioned machinery and equipment frames.

Key Features

• M8 x 1.25 metric thread size, 55 mm length under head
• Grade 8.8 steel construction for consistent tensile strength
• Zinc-plated finish provides basic corrosion protection
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 13 mm hex drive size for standard wrench and socket tooling

Compatibility

Designed as a standard DIN 931 and ISO 4014 compliant metric hex head cap screw suitable for M8 x 1.25 threaded applications in steel and aluminum assemblies.

Installation Notes

Installation requires a 13 mm wrench or socket. Always confirm thread pitch and engagement length before fastening to avoid cross-threading or under-engagement. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 8.8 fasteners. Inspect the zinc-plated finish for damage before installation in corrosion-sensitive environments.
