Value Collection HC3XX20080-001BX M20 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX20080-001BX is a fully threaded hex head cap screw conforming to DIN 933. Machined from Grade 316 austenitic stainless steel (A4), it delivers strong resistance to corrosion and oxidation in wet, chemical, and marine environments. The M20 x 2.50 thread form and 80 mm length under head suit medium-to-heavy structural and mechanical fastening applications. The bright, uncoated finish maintains dimensional accuracy and is compatible with standard metric hardware. This fastener is installed by maintenance technicians, pipefitters, millwrights, and mechanical contractors working on process equipment, structural assemblies, and fluid system components.

This screw is suited for industrial, commercial, and marine installations where stainless steel fasteners are specified. Typical use cases include pipe flange assemblies, pump and valve mounting, food-processing equipment, and coastal or chemical-exposure environments where carbon steel fasteners would corrode. The DIN 933 standard ensures dimensional interchangeability with other metric hardware in the same specification family.

Key Features

• Grade 316 austenitic stainless steel (A4) for superior corrosion resistance in harsh environments
• Fully threaded per DIN 933 standard for maximum thread engagement across the full shank
• M20 x 2.50 metric thread with 80 mm length under head for heavy fastening applications
• 30 mm hex drive size compatible with standard metric wrenches and sockets
• Bright, uncoated finish maintains precise dimensions and consistent fit with metric hardware

Compatibility

Designed as a DIN 933-compliant metric hex head cap screw for use wherever an M20 x 2.50 x 80 mm fully threaded fastener in Grade 316 stainless steel is specified.

Installation Notes

Installation is performed by qualified tradespeople using metric wrenches or sockets sized to the 30 mm hex. De-energize, depressurize, or otherwise isolate the assembly before replacing fasteners in live systems. Apply an anti-seize compound compatible with stainless steel to prevent galling when torquing 316 SS fasteners. Torque to the value specified by the equipment manufacturer or applicable engineering standard — do not rely on generic torque tables without confirming material and joint requirements.
