Value Collection 217142 M8x1.25x20mm Hex Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION 217142 is a metric hex head cap screw designed for general-purpose fastening in applications where corrosion resistance is required. Built from 18-8 austenitic stainless steel (Grade A2), this screw offers solid resistance to rust and oxidation in both indoor and outdoor environments. The M8 x 1.25 thread profile follows standard metric coarse pitch dimensions, with a 20 mm length under head and a 13 mm hex drive. It is fully threaded from tip to head and conforms to DIN 933, making it a direct fit wherever that standard is specified.

This screw is used across a wide range of trades and industrial settings, including mechanical, plumbing, HVAC equipment assembly, electrical enclosures, and structural component fastening. Fully threaded construction makes it well suited for thinner material joints and through-bolt applications. Stainless construction suits installations where exposure to moisture, mild chemicals, or outdoor conditions is expected. Technicians, millwrights, and maintenance professionals routinely stock this size for both original equipment assembly and field repair work.

Key Features

• 18-8 austenitic stainless steel construction provides corrosion and oxidation resistance
• Grade A2 material meets DIN 933 dimensional and material requirements
• M8 x 1.25 metric coarse thread for broad compatibility with standard metric hardware
• Fully threaded from tip to bearing face for maximum thread engagement in shallow joints
• 13 mm hex drive fits standard metric sockets and wrenches
• 20 mm length under head suits a range of clamping and through-bolt configurations

Compatibility

Designed as a DIN 933-compliant replacement or standard-stock metric hex head cap screw for any application specifying M8 x 1.25 thread pitch and 20 mm length under head in 18-8 stainless steel.

Installation Notes

Installation is performed with a standard 13 mm metric socket, box wrench, or hex-drive tool. Ensure mating threads are clean and free of debris before installation to prevent galling, which is common with stainless steel fasteners. Apply an anti-gall lubricant or anti-seize compound to the threads prior to torquing. Do not mix metric and unified thread fasteners, and verify thread pitch with a thread gauge before installation in critical joints.
