Value Collection HC3X16020-010BX M16 Hex Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION HC3X16020-010BX is a fully threaded hex head cap screw designed for metric fastening applications in industrial, mechanical, and trade assembly work. Built from 18-8 austenitic Grade A2 stainless steel with a bright uncoated finish, this fastener delivers solid corrosion resistance in wet or chemically exposed environments. The screw follows the M16 x 2.00 thread specification with a 20 mm length under the head, a 24 mm hex drive, and conforms to DIN 933 standards. It is sold in a minimum order quantity of 10 pieces and is suited for both shop and field use by maintenance technicians, pipefitters, and mechanical contractors.

This cap screw is commonly used in HVAC equipment mounting, pump and compressor assembly, pipe flange connections, and general mechanical fastening where metric hardware and corrosion resistance are required. The fully threaded shank provides consistent thread engagement across the full length, making it well suited for thin material applications or through-bolt installations without a nut plate. Stainless construction makes it a practical choice for outdoor equipment, rooftop units, and wet mechanical rooms where carbon steel fasteners would corrode prematurely.

Key Features

• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance in wet and outdoor environments
• Fully threaded shank per DIN 933 standard for maximum thread engagement
• M16 x 2.00 metric thread with 20 mm length under head

• Minimum order of 10 pieces ensures job-site quantity availability

Compatibility

Designed as an OEM-style metric replacement fastener for applications requiring M16 x 2.00 fully threaded hex head cap screws conforming to DIN 933.

Installation Notes

Installation is performed by mechanical contractors, HVAC technicians, pipefitters, or maintenance personnel using a 24 mm open-end wrench or socket. Always de-energize equipment and relieve system pressure before replacing structural or pressure-boundary fasteners. Use appropriate thread lubricant or anti-seize compound when installing stainless fasteners into stainless or aluminum tapped holes to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.
