Value Collection 815047PR M8x1.25x35mm Hex Cap Screw

Product Description

The VALUE COLLECTION 815047PR is a metric hex head cap screw designed for general-purpose mechanical fastening in industrial, maintenance, and manufacturing applications. It is manufactured from Grade 8.8 steel with a zinc-plated finish that provides baseline corrosion resistance for indoor and light-duty outdoor use. The fastener features an M8 x 1.25 thread profile with a 35 mm length under the head and is partially threaded per DIN 931 and ISO 4014 standards. The 13 mm hex drive accommodates standard metric wrenches and sockets. Licensed trades and maintenance technicians use this screw when a controlled-clamp fastener with a defined grip length is required.

This cap screw is suited for metal-to-metal joints in light machinery, HVAC equipment frames, bracket assemblies, and general structural connections where a partially threaded shank is needed to maintain shear strength across the joint. The partial thread design allows the unthreaded shank to sit in the clearance hole of the clamped material, reducing lateral movement. It is sized for standard M8 tapped holes or nuts and is appropriate for residential and commercial maintenance work requiring metric fasteners.

Key Features

• Grade 8.8 steel construction provides a minimum tensile strength appropriate for medium-duty clamping applications
• Zinc-plated finish offers corrosion resistance for indoor and sheltered environments
• Partially threaded shank per DIN 931 and ISO 4014 for improved shear load performance
• M8 x 1.25 metric thread — standard pitch for M8 fastener applications
• 13 mm hex head fits common metric sockets and open-end wrenches
• 35 mm length under head suits a range of standard material stack thicknesses

Compatibility

Designed for use with M8 x 1.25 metric nuts and tapped holes conforming to DIN 931 and ISO 4014 standards. Suitable as a replacement or supplemental fastener in any assembly calling for a partially threaded M8 x 1.25 x 35 mm hex cap screw in Grade 8.8 steel.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or maintenance professional familiar with metric fastener torque requirements for Grade 8.8 hardware. Always ensure the mating thread or nut is clean and free of debris before installation. Use a calibrated torque wrench and consult the equipment manufacturer's torque specification for M8 Grade 8.8 fasteners. Do not exceed the rated clamp load or mix with non-metric or mismatched grade hardware.
