Value Collection 815509PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 815509PR is a metric hex head cap screw designed for general-purpose mechanical fastening in industrial, commercial, and trade applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw provides reliable tensile strength and basic corrosion resistance. The M8 x 1.25 thread size with a 100 mm length under head and 13 mm hex drive makes it a standard choice for medium-duty assemblies. The partial threading conforms to DIN 931 and ISO 4014 standards, ensuring dimensional consistency and interchangeability across metric fastener applications. Installation requires a 13 mm wrench or socket.

This cap screw is suited for use in fabrication shops, equipment assembly, HVAC structural mounting, plumbing equipment brackets, and general mechanical maintenance. The partial thread design is appropriate for fastening through clearance holes where the unthreaded shank provides clamping load without thread engagement across the full grip length. It is commonly installed by millwrights, maintenance technicians, HVAC mechanics, and plumbers securing equipment frames, panels, and mechanical components.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength suitable for structural and equipment fastening
• Zinc-plated finish offers basic corrosion protection for indoor and sheltered outdoor use
• Partial thread per DIN 931 and ISO 4014 for consistent dimensional compliance and interchangeability
• M8 x 1.25 metric thread standard with 13 mm hex drive for common wrench and socket compatibility
• 100 mm length under head accommodates thicker stacked assemblies and clearance-hole applications

Compatibility

Designed as a standard metric replacement or service fastener for any application requiring an M8 x 1.25 partially threaded hex head cap screw conforming to DIN 931 or ISO 4014 dimensional standards.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener torque requirements for Grade 8.8 hardware. Always ensure mating threads are clean and free of debris before installation. Do not exceed the rated proof load of the fastener; consult a Grade 8.8 torque specification chart appropriate for the thread size and lubrication condition. Minimum order quantity for this part is 50 units.
