Holo-krome 77128 M6 X 1.00 Hex Socket Cap Screw 16mm Ss

Product Description

The HOLO-KROME 77128 is a metric hex socket cap screw designed for secure, high-torque fastening in mechanical, industrial, and trade applications. Manufactured from Austenitic Grade A2 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet and chemically active environments. The M6 x 1.00 thread size and 16mm length under head make it well suited for compact assembly work where a flush or countersunk profile is not required. Drive engagement is through a standard internal hex socket, which allows high clamping force without slipping or burring the head. Machinists, millwrights, and field technicians working on equipment assembly or structural fastening will find this screw a reliable choice for metric fastener needs.

This screw is commonly used in HVAC equipment brackets, pump and motor mounts, enclosure hardware, and general mechanical assemblies that require a corrosion-resistant metric fastener. The fully threaded shank provides consistent thread engagement along the entire grip length, making it appropriate for thin-material applications and through-bolt configurations. It meets ISO 3506-1 and ISO 4762 fastener standards, which are widely specified in mechanical engineering drawings and OEM equipment documentation.

Key Features

• M6 x 1.00 metric thread, fully threaded shank for maximum engagement
• 16mm length under head suits compact through-bolt and tapped-hole applications
• Austenitic Grade A2 stainless steel construction for corrosion resistance
• Bright, uncoated finish maintains dimensional accuracy for close-tolerance fits
• Internal hex socket drive reduces cam-out and allows high installation torque
• Meets ISO 3506-1 and ISO 4762 international fastener standards

Compatibility

Designed as an OEM-style replacement or general-use metric hex socket cap screw compatible with any tapped M6 x 1.00 metric threaded hole requiring a 16mm under-head length fastener per ISO 4762 specifications.

Installation Notes

Installation requires a correctly sized hex key or Allen driver to avoid rounding the socket. Always verify the receiving thread is clean and properly tapped to M6 x 1.00 before installation. Apply appropriate thread-locking compound or anti-seize as specified by the equipment manufacturer when required. Power down or de-energize any equipment before accessing fastened components in electrical or HVAC assemblies.
