Holo-krome 76036 Hex Socket Cap Screw M3 X 0.50 Metric

Product Description

The HOLO-KROME 76036 is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, tooling, and industrial equipment. Sized at M3 x 0.50 with a 25 mm length under head, this screw is partially threaded and features an internal hex drive for torque application with a standard hex key or Allen driver. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suitable for demanding clamping and structural fastening applications. The black oxide coating provides mild corrosion resistance and a consistent dark finish. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers across a wide range of industries.

This screw is suited for use in machine tool fixtures, jigs, mechanical subassemblies, and precision equipment where a compact-head, high-strength metric fastener is required. The M3 thread size and 25 mm body length make it appropriate for thin to medium-thickness material stacks where partial threading is needed to achieve proper clamping load. It is commonly used in both light industrial and OEM manufacturing environments where metric fastener standards are specified.

Key Features

• Alloy steel construction at grade 12.9 for high tensile and proof load capacity
• Partially threaded shank for accurate clamping across material stacks
• Internal hex socket drive compatible with standard metric hex keys
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Conforms to 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 suitable for any application specifying an M3 x 0.50 grade 12.9 alloy steel fastener with a 25 mm length under head.

Installation Notes

Installation is performed with a metric hex key or socket driver sized for M3 cap screws. Always verify thread engagement depth and mating thread condition before final tightening. Do not mix metric and inch-series fasteners in the same assembly. Apply thread-locking compound or appropriate preload torque per the equipment manufacturer's specifications when vibration resistance is required.
