Value Collection HC3XX12055-025BX M12 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX12055-025BX is a fully threaded hex head cap screw manufactured from Grade 316 austenitic stainless steel to the A4 material classification. It features an M12 x 1.75 thread profile with a 55 mm length under the head, a 19 mm hex drive, and meets DIN 933 dimensional standards. The 316 alloy provides strong resistance to chlorides, acids, and marine environments, making it suitable for demanding service conditions where carbon steel or lower-grade stainless fasteners would corrode. Licensed tradespeople and maintenance technicians install this fastener in mechanical, plumbing, and structural assemblies requiring corrosion-resistant hardware.

This fastener is appropriate for use in marine, coastal, chemical processing, food processing, and industrial environments where exposure to moisture, salt, or corrosive media is a concern. It is a standard metric fastener used in equipment assembly, pipe flange bolting, structural bracketing, and general mechanical maintenance across commercial and industrial applications. The fully threaded shank provides consistent thread engagement from the bearing face to the tip, which is preferred in through-bolt applications and shorter clamping lengths.

Key Features

• Grade 316 austenitic stainless steel with A4 classification for superior corrosion resistance
• Fully threaded shank per DIN 933 standard for consistent engagement across the full bolt length
• M12 x 1.75 metric thread profile with 55 mm length under head
• 19 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no coating to crack, flake, or interfere with torque values
• Minimum order quantity of 5 units

Compatibility

Designed as a DIN 933-compliant M12 x 1.75 fully threaded hex head cap screw suitable for any application requiring a metric Grade 316 stainless fastener with a 19 mm hex drive.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or licensed tradesperson familiar with metric fastener specifications. Always verify thread pitch and material compatibility with the mating nut or tapped hole before installation. Use calibrated torque equipment and apply an appropriate anti-seize compound when joining stainless to stainless components to prevent galling. Do not use impact tools set above rated torque ranges on stainless steel fasteners, as galling can cause permanent seizure.
