Value Collection HC3XX20075-001BX M20 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX20075-001BX is a fully threaded hex head cap screw manufactured from Grade 316 austenitic stainless steel meeting the A4 material classification. It follows the DIN 933 standard for fully threaded hex bolts, with an M20 x 2.50 thread profile and a 75 mm length under the head. The 30 mm hex drive size accepts standard metric wrenching. Grade 316 stainless provides elevated corrosion resistance compared to 304 due to its molybdenum content, making it suitable for wet, marine, or chemically exposed environments. This fastener ships individually and is appropriate for mechanical, structural, or equipment assembly applications requiring a metric stainless fastener.

This screw is used across a wide range of industrial and commercial applications where corrosion resistance and metric thread standards are required. Typical install scenarios include marine hardware, chemical processing equipment, food service structures, HVAC structural assemblies, pump and compressor mounting, and outdoor or coastal installations. The fully threaded shank allows for engagement along the entire length, which is useful when threading into deep holes or when using a full-engagement nut. Licensed tradespeople and assembly technicians working in corrosive environments regularly specify A4-316 fasteners for long-term joint integrity.

Key Features

• Grade 316 austenitic stainless steel with A4 classification for superior corrosion resistance in harsh environments
• Fully threaded per DIN 933 standard — thread engagement along the entire 75 mm shank length
• M20 x 2.50 metric thread profile for compatibility with standard metric nuts and tapped holes
• 30 mm hex drive accepts standard metric open-end, box, or socket wrenches
• Bright uncoated finish — no plating to flake, contaminate, or interfere with stainless-to-stainless galling considerations
• Single-piece packaging with no minimum order quantity above one unit

Compatibility

Designed as a standard DIN 933 fully threaded hex head cap screw in M20 x 2.50 thread size, compatible with any application requiring a metric M20 hex bolt in Grade 316 austenitic A4 stainless steel.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with metric fastener standards. When installing stainless steel fasteners, apply an appropriate anti-seize compound to reduce the risk of galling between mating stainless surfaces. Verify thread fit and torque to the joint designer's specification using a calibrated torque wrench — no torque value is specified by the manufacturer for this fastener. Follow applicable mechanical or structural codes for the installation environment.
