Holo-krome 76344 M10x1.5 Hex Socket Cap Screw 80mm

Product Description

The HOLO-KROME 76344 is a metric hex socket cap screw designed for high-strength fastening in mechanical assemblies, tooling fixtures, and industrial equipment. Manufactured from alloy steel with a grade 12.9 rating, this screw delivers tensile strength suited for demanding load-bearing applications. The black oxide coating provides mild corrosion resistance and reduces light reflection during service. The M10 x 1.50 thread profile with an 80 mm length under head and partial threading makes it a standard choice for fastening through thick plates, flanges, or structural machine components. Drive engagement is through an internal hex socket, installed with a standard metric hex key or Allen driver.

This screw is used in industrial maintenance, precision machining, OEM equipment assembly, and structural fabrication where a low-profile, high-strength threaded fastener is required. The grade 12.9 alloy steel construction suits applications subject to vibration, high clamp loads, or elevated stress. Typical installers include millwrights, mechanical assemblers, and maintenance machinists working on pumps, presses, conveyor systems, and similar equipment. Partial threading provides full engagement in standard clearance-hole and tapped applications.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• M10 x 1.50 metric thread, 80 mm length under head
• Partially threaded shank for standard clearance-hole fastening applications
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Internal hex socket drive compatible with standard metric hex keys
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric hex socket cap screw, compatible with any M10 x 1.50 tapped hole or threaded insert conforming to ANSI B1.13M metric thread standards.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated metric hex key or torque wrench set to the appropriate grade 12.9 M10 torque specification from the fastener manufacturer or engineering drawing. Always de-energize and lock out equipment before replacing or tightening fasteners in mechanical assemblies. Do not substitute a lower-grade fastener in any application specified for grade 12.9. Thread engagement depth should meet minimum requirements per the applicable engineering standard.
