Holo-krome 76260 Hex Socket Cap Screw M8 X 1.25 50mm

Product Description

The HOLO-KROME 76260 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade installations. It features an M8 x 1.25 thread and a 50 mm length under head with partial threading. Manufactured from alloy steel with a black oxide finish, it meets Material Grade 12.9, making it suitable for applications that require elevated tensile strength and reliable clamping force. The internal hex drive accepts a standard hex key for precise torque application in confined spaces. This fastener weighs approximately 0.02 pounds per unit.

This screw is used in a wide range of mechanical assemblies, equipment maintenance, and fabrication work where a metric-standard fastener is required. The partial threading design provides a stronger grip in thick materials and reduces the risk of cross-threading in blind holes. It is commonly installed by machinists, millwrights, industrial maintenance technicians, and HVAC or equipment service professionals when securing panels, brackets, or mechanical components that specify an M8 metric fastener.

Key Features

• M8 x 1.25 metric thread with 50 mm length under head
• Partial threading for improved load distribution in thick substrates
• Material Grade 12.9 alloy steel for high tensile and proof load strength
• Black oxide coating provides mild corrosion resistance and reduced light reflection
• Internal hex socket drive allows use in tight clearance areas
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard M8 x 1.25 metric hex socket cap screw conforming to DIN 912 and ISO 4762 dimensions, suitable as a direct replacement in any assembly specifying those standards at Material Grade 12.9.

Installation Notes

Install with a properly sized metric hex key or hex socket bit to avoid rounding the drive recess. De-energize or lock out any equipment before replacing fasteners on live assemblies. Verify thread engagement depth meets design specifications before applying final torque. Do not substitute this Grade 12.9 fastener with a lower-grade screw in structural or high-load applications.
