Value Collection HC3XX20070-001BX M20 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX20070-001BX is a fully threaded hex head cap screw manufactured to DIN 933 standards. It measures M20 x 2.50 thread pitch with a 70 mm length under head and a 30 mm hex drive size. The fastener is made from Grade 316 austenitic stainless steel (A4 grade), which provides strong resistance to corrosion and oxidation in demanding environments. The bright, uncoated finish is left as-machined with no additional plating or coating applied. This screw is commonly installed by licensed mechanical contractors, pipefitters, and industrial maintenance technicians working on structural, piping, and equipment assemblies.

This hex head cap screw is suited for metric fastener applications where corrosion resistance is a priority, including marine, chemical processing, food service, and outdoor industrial installations. The DIN 933 full-thread configuration provides maximum thread engagement across the full length of the fastener shank, making it a dependable choice for through-bolted connections and close-tolerance assemblies in both light and heavy industrial settings.

Key Features

• Full threading along the entire 70 mm length under head for maximum thread engagement
• Grade 316 austenitic stainless steel (A4) for superior corrosion and chemical resistance
• M20 x 2.50 metric thread size conforming to standard metric thread pitch
• 30 mm hex drive size compatible with standard metric wrenches and sockets
• DIN 933 standard for reliable dimensional consistency
• Bright, uncoated finish - no plating or coating to affect torque or thread fit

Compatibility

Designed as a DIN 933 fully threaded metric hex head cap screw suitable for M20 x 2.50 threaded fastener applications requiring Grade 316 stainless steel material.

Installation Notes

Installation should be performed by qualified mechanical or industrial maintenance personnel following applicable fastener and structural codes. Confirm mating thread pitch and material compatibility before installation, particularly in dissimilar-metal assemblies where galvanic corrosion may be a concern. Use a calibrated torque wrench with a properly sized metric socket to achieve proper clamp load without galling the stainless threads. Applying an anti-seize compound to the threads is a common field practice with stainless fasteners to prevent thread galling during installation and future removal.
