Value Collection R80260422 Hex Head Cap Screw M20x2.50mm

Product Description

The VALUE COLLECTION R80260422 is a metric hex head cap screw designed for bolted assemblies requiring corrosion-resistant fastening in industrial, mechanical, and structural applications. The fastener is partially threaded with a coarse M20x2.50mm thread form and a 100mm length under the head. It is manufactured from Grade 18-8 stainless steel and left uncoated, providing natural resistance to rust and oxidation. The 30mm hex drive accommodates standard metric wrenches and sockets. Licensed tradespeople, millwrights, maintenance mechanics, and fabricators are the typical installers for fasteners of this class.

This cap screw is suited for general-purpose metric fastening in environments where corrosion resistance matters, such as food processing facilities, marine adjacent structures, chemical handling equipment, and outdoor mechanical assemblies. The partial thread engagement allows for clamping force to be distributed along the unthreaded shank when passing through clearance holes, which is standard practice in structural bolted connections and machinery frames.

Key Features

• M20x2.50mm metric coarse thread form for compatibility with standard metric nuts and tapped holes
• 100mm length under head with partial threading for shank-bearing load applications
• Grade 18-8 stainless steel construction for corrosion and oxidation resistance
• Uncoated finish — no plating to degrade or flake in harsh environments
• 30mm hex head drive accepts standard metric sockets and open-end wrenches

Compatibility

Designed as an OEM-style replacement or standard metric fastener for any assembly requiring an M20x2.50mm coarse-thread hex head cap screw with a 100mm under-head length in 18-8 stainless steel.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or tradesperson familiar with metric fastener standards. De-energize, depressurize, or otherwise isolate the assembly before disassembling existing hardware. Use a calibrated torque wrench sized for the 30mm hex drive and follow the torque specifications provided by the equipment manufacturer for M20 stainless fasteners. Apply an appropriate anti-seize compound if the fastener will be installed in an environment prone to galling, which is common with stainless steel threads.
