Holo-krome 76234 Hex Socket Cap Screw M8 X 1.25 Alloy Steel

Product Description

The HOLO-KROME 76234 is a metric hex socket cap screw designed for high-strength fastening in demanding industrial and mechanical applications. It features an M8 x 1.25 thread, a length under head of approximately 0.71 inches (18 mm), and full threading along its entire shank. Manufactured from alloy steel to material grade 12.9, this fastener delivers exceptional tensile and proof load capacity well above standard grade hardware. The black oxide coating provides a uniform dark finish and a modest level of corrosion resistance. Installation requires a hex key or Allen driver sized to the M8 socket specification. Maintenance technicians, millwrights, and mechanical assemblers are the primary installers.

This cap screw is suited for precision assemblies, machine tool fixtures, hydraulic component mounting, and structural fastening where a flush or low-profile head is required. The fully threaded shank allows maximum thread engagement across a range of material thicknesses. It is sold in multiples of 100 units, making it appropriate for production-line use, MRO restocking, and service shop inventory.

Key Features

• M8 x 1.25 thread with full threading along the entire shank length
• Length under head: 0.71 inches (18 mm)
• Alloy steel construction at material grade 12.9 for high-load applications
• Black oxide finish for a uniform appearance and mild corrosion resistance
• Hex socket drive accepts standard Allen or hex key tooling
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as a metric hex socket cap screw conforming to ISO 4762 and ANSI B1.13M, suitable for use in any application requiring an M8 x 1.25 grade 12.9 alloy steel socket cap fastener.

Installation Notes

Installation should be performed by qualified mechanical technicians or assemblers using a properly sized hex key or Allen driver. De-energize and lock out any equipment before servicing fastened assemblies. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque capacity of the fastener material grade, and consult the relevant equipment service documentation for specified torque values.
