Value Collection 797732BR M18 Hex Head Cap Screw Din 931

Product Description

The VALUE COLLECTION 797732BR is a metric hex head cap screw engineered for industrial, mechanical, and structural fastening applications. It features an M18 x 2.50 thread profile with a 140 mm length under head and partial threading along the shank. Manufactured from 18-8 austenitic Grade A2 stainless steel, this fastener resists corrosion in wet, chemical, and outdoor environments. The bright, uncoated finish preserves the natural stainless appearance and is free from any plating or surface treatment. A 27 mm hex drive allows installation with standard metric wrenches or hex-drive tooling. Compliance with DIN 931 ensures dimensional consistency for precision assemblies.

This screw is suited for use in manufacturing equipment, process piping assemblies, marine hardware, food-processing machinery, and general structural connections where corrosion resistance and metric dimensional standards are required. Partial threading is appropriate for applications where clamping force must be distributed across an unthreaded grip length, such as in flanged joints or multi-layer material stacks. It is typically installed by machinists, millwrights, pipefitters, and maintenance technicians working in metric-standard environments.

Key Features

• M18 x 2.50 metric thread profile for broad compatibility with metric-tapped components
• 140 mm length under head provides adequate grip length for thick material assemblies
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance in wet and chemical environments
• Partially threaded shank suits flanged joints and applications requiring a defined grip zone
• 27 mm hex head accommodates standard metric wrenches and socket sets
• Conforms to DIN 931 for dimensional consistency in precision and industrial assemblies

Compatibility

Designed as a DIN 931 partially threaded hex head cap screw for use in any metric-tapped M18 x 2.50 application requiring 18-8 Grade A2 stainless steel fasteners.

Installation Notes

Installation should be performed by qualified machinists, pipefitters, or maintenance technicians familiar with metric fastener standards. Apply appropriate thread engagement depth per engineering specifications and use a calibrated torque wrench to reach the required clamp load without overstressing stainless steel threads, which are susceptible to galling. Anti-seize compound is commonly applied to stainless fastener threads to reduce galling risk during installation. De-energize or depressurize any equipment fully before replacing fasteners in live mechanical assemblies.
