Holo-krome 76126 M5 X 0.80 Hex Socket Cap Screw 22mm

Product Description

The HOLO-KROME 76126 is a metric hex socket cap screw designed for high-strength mechanical fastening applications. It features an M5 x 0.80 thread profile with a 22 mm length under head and is fully threaded along its shank. The fastener is machined from alloy steel to a 12.9 material grade, which is among the highest strength classifications for metric fasteners, making it suitable for assemblies under significant tensile and shear loading. A black oxide coating provides moderate corrosion resistance and reduces light reflection on exposed surfaces. This screw is driven with a hex socket or Allen key tool and is installed by machinists, maintenance technicians, and mechanical contractors.

This fastener is suited for use in precision mechanical assemblies, industrial equipment, tooling fixtures, and structural fastening applications where high-clamp-load performance is required. The fully threaded configuration allows maximum thread engagement across the full 22 mm length, making it well suited for thin-material applications and through-bolt configurations. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, supporting use in both domestic and internationally specified assemblies. This SKU is sold individually but carries a minimum order quantity of 100 units.

Key Features

• M5 x 0.80 metric thread with 22 mm length under head
• Fully threaded shank for maximum thread engagement
• Alloy steel construction, 12.9 material grade for high tensile strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Hex socket drive compatible with standard Allen key and socket tooling
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric hex socket cap screw conforming to ISO 4762 and ANSI B1.13M, compatible with any M5 x 0.80 threaded hole or insert in mechanical assemblies, fixtures, and equipment requiring a 12.9-grade fastener.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a properly sized hex socket driver or Allen key to avoid rounding the drive socket. Ensure threaded holes or nuts are clean and free of debris before installation. Apply thread-locking compound or specified fastener torque per the equipment manufacturer's assembly documentation. Do not mix metric and unified thread fasteners in the same assembly.
