Holo-krome 76172 Hex Socket Cap Screw M6 X 1.00 20mm

Product Description

The HOLO-KROME 76172 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features an M6 x 1.00 thread and a 20 mm length under head with full threading along the entire shank. Manufactured from alloy steel at material grade 12.9, this fastener delivers a high tensile load capacity suited for demanding clamping and structural connections. The black oxide finish provides a mild level of corrosion resistance and reduces light reflection in finished assemblies. Licensed machinists, millwrights, and mechanical contractors are the typical installers.

This screw is used wherever a compact, high-torque hex socket drive is required in metric threaded holes. Common applications include machine frames, fixtures, tooling plates, hydraulic component mounting, and general industrial equipment assembly. The fully threaded shank maximizes thread engagement in thin or shallow blind holes. Its M6 x 1.00 thread form and grade 12.9 rating make it a standard choice in precision mechanical assemblies requiring controlled preload.

Key Features

• M6 x 1.00 thread size with 20 mm length under head
• Fully threaded shank for maximum thread engagement
• Alloy steel construction, material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Hex socket (Allen) drive type for high torque application in tight spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement and standard metric cap screw for applications requiring an M6 x 1.00 hex socket drive fastener conforming to DIN 912 and ISO 4762 specifications.

Installation Notes

Installation requires a correctly sized hex key or Allen bit driver matched to the M6 socket head. Always verify the mating threaded hole is clean, properly tapped to M6 x 1.00, and free of debris before driving the fastener. Apply thread-locking compound or specified fastener lubricant according to the assembly specification where preload control is critical. Follow applicable ASME or equipment manufacturer torque specifications for grade 12.9 fasteners when tightening.
