Holo-krome 76324 Hex Socket Cap Screw M10x1.50 55mm

Product Description

The HOLO-KROME 76324 is an M10 x 1.50 hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and tooling fixtures. The screw features a 55 mm length under head with partial threading and is driven by a standard hex (Allen) key. Manufactured from alloy steel at a Grade 12.9 strength rating, it carries a black oxide finish that provides a moderate level of corrosion resistance and reduces galling during installation. This fastener meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, making it suitable for precision-fit metric applications.

This screw is commonly used in machine tool construction, hydraulic manifold assemblies, jig and fixture work, and general industrial equipment where high clamp load and a low-profile head are required. The partial threading allows for a smooth shank section to seat against bearing surfaces or clearance holes, providing accurate location and shear resistance. Machinists, millwrights, and industrial maintenance technicians regularly specify Grade 12.9 socket cap screws for critical joint applications where standard hardware would be insufficient.

Key Features

• Grade 12.9 alloy steel construction delivers high tensile strength for demanding fastening applications
• Partial threading provides a smooth shank for precise location and shear load resistance
• Black oxide finish reduces surface friction and offers light corrosion protection
• Hex socket drive accepts standard Allen keys and hex bit drivers
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric hex socket cap screw for use in any M10 x 1.50 threaded hole requiring a Grade 12.9, DIN 912 or ISO 4762 style fastener with a 55 mm length under head.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians using a properly sized hex key or socket bit rated for Grade 12.9 torque requirements. De-energize and lock out all equipment before servicing fastened assemblies. Apply thread lubricant or anti-seize only if the joint design calls for it, as dry torque values differ from lubricated values. Do not substitute a lower-grade fastener in any location specified for Grade 12.9 hardware.
