Holo-krome 76140 Hex Socket Cap Screw M5 X 0.80 Metric

Product Description

The HOLO-KROME 76140 is an M5 x 0.80 metric hex socket cap screw with a 40 mm length under head. It is manufactured from alloy steel at material grade 12.9, the highest standard strength class for metric fasteners, and finished with a black oxide coating that provides moderate corrosion resistance and a low-reflectance appearance. The screw is partially threaded and driven with a hex (Allen) socket tool. It is used in precision mechanical assemblies, machine tooling, fixtures, and structural connections where high clamping force in a compact head profile is required. Maintenance technicians, machinists, and industrial assemblers commonly install this fastener.

This screw is suited for applications requiring a high-strength metric fastener in tight-clearance environments. The low-profile socket cap head makes it a practical choice for machine frames, brackets, jigs, and equipment panels where standard hex-head fasteners cannot be accessed easily. The black oxide finish is typical for interior or lightly controlled environments. It conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, making it compatible with metric-specification engineering and manufacturing workflows across a wide range of industries.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Black oxide finish provides mild corrosion protection and reduces surface glare
• Partially threaded shank allows precise shank-to-bore fit in close-tolerance assemblies
• Hex socket drive for use with standard Allen keys or hex bit drivers
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style metric replacement or new-installation fastener for any application specifying an M5 x 0.80 hex socket cap screw per DIN 912 or ISO 4762 at grade 12.9.

Installation Notes

Installation is performed by machinists, maintenance technicians, or industrial assemblers using a correctly sized hex key or socket bit. Always ensure the mating threaded hole is clean and free of debris before driving. Do not exceed the rated clamp load for the material grade, and do not use impact drivers at full torque without a verified torque specification for the joint. Black oxide fasteners used in corrosive or outdoor environments should be inspected regularly for surface degradation.
