Value Collection 815220PR M20 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 815220PR is a metric hex head cap screw designed for general mechanical assembly and structural fastening applications. It features an M20 x 2.50 thread size with a 30 mm length under head and is fully threaded from tip to head. Manufactured from Grade 8.8 steel with a zinc plating finish, this fastener delivers solid tensile strength and basic corrosion resistance in a wide range of bolted connections. The 30 mm hex key size conforms to DIN 933 and ISO 4017 dimensional standards, making it a direct fit in metric fastening systems. Installers and maintenance technicians working in fabrication, equipment assembly, and structural work will find this a reliable off-the-shelf option.

This hex head cap screw is suited for metric fastening applications in industrial, commercial, and light structural settings. Fully threaded geometry makes it appropriate for through-hole applications where thread engagement along the full shank length is required. It is commonly used in machine assembly, frame fabrication, and equipment maintenance where M20 coarse-pitch fasteners are specified. The zinc plating provides a measure of protection in indoor and mildly corrosive environments. This item is sold in minimum order quantities of 5 units.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener specifications and torque requirements for Grade 8.8 hardware. Always verify thread engagement depth and hole clearance before installing. Use a calibrated torque wrench and follow the torque specifications provided by the equipment or structure manufacturer. Inspect the mating threads and seating surface for damage before fastening.
