Value Collection HC1XX20070 M20 Hex Head Cap Screw A4 Ss

Product Description

The VALUE COLLECTION HC1XX20070 is a metric hex head cap screw designed for applications requiring corrosion-resistant fastening in demanding environments. Manufactured from Grade 316 austenitic stainless steel to the A4 material grade, this fastener resists oxidation, chemical exposure, and moisture better than standard stainless grades. The screw measures M20 x 2.50 mm thread pitch with a 70 mm length under head and features partial threading per DIN 931, EN 24014, and ISO 4014 standards. A licensed mechanic, industrial maintenance tech, or pipefitter installs this type of fastener in structural, plumbing, and process-equipment assemblies where a bright, uncoated finish is acceptable.

This fastener is suited for metric-standard assemblies in marine, chemical processing, food service, and general industrial environments where Grade 316 stainless steel is specified for its molybdenum-enhanced corrosion resistance. The partial threading design allows for improved clamping force in through-bolt applications with thicker material stacks. The 30 mm hex drive size accepts standard metric wrenches and sockets, making installation straightforward in the field or on the bench. Both residential and commercial maintenance professionals use this screw wherever an ISO 4014 or DIN 931 compliant fastener is called out on drawings or specs.

Key Features

• Grade 316 austenitic stainless steel with A4 material grade for superior corrosion resistance
• Partially threaded shank per DIN 931, EN 24014, and ISO 4014 standards
• M20 x 2.50 mm metric thread with 70 mm length under head
• 30 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no plating or coating to degrade in harsh environments

Compatibility

Designed as an OEM-style metric replacement or new-installation fastener for assemblies specifying an ISO 4014 or DIN 931 partially threaded hex cap screw in M20 x 2.50 mm size with Grade 316 or A4 stainless steel material.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener standards. Verify mating thread condition and hole depth before installation to avoid cross-threading or bottoming out the fastener. Use a calibrated torque wrench and apply fastener torque values as specified by the equipment manufacturer or applicable structural code. Do not mix stainless steel fasteners with dissimilar metals in submerged or high-chloride environments without reviewing galvanic compatibility.
