Holo-krome 76456 Hex Socket Cap Screw M16 X 2.00

Product Description

The HOLO-KROME 76456 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, machinery, and industrial equipment. Sized M16 x 2.00 with a 70 mm length under head, this partially threaded fastener is manufactured from alloy steel with a black oxide finish. It carries a material grade of 12.9, indicating exceptional tensile and proof load strength suited to demanding clamping applications. The hex socket drive accepts a standard hex key or Allen-style bit. Black oxide coating provides mild corrosion resistance and a consistent dark appearance. Installation and removal require no special tooling beyond the correct hex key size for M16 cap screws.

This fastener is well suited for industrial maintenance, OEM assembly, and repair work where a high-torque, recessed-drive cap screw is required. It is partially threaded, making it appropriate for applications where the shank must pass through a clearance hole before engaging a threaded bore. Mechanical contractors, millwrights, maintenance technicians, and equipment assemblers are the typical installers. Sold individually per the single-unit package quantity.

Key Features

• M16 x 2.00 thread size with 70 mm length under head
• Partially threaded shank for use with clearance-hole and threaded-bore assemblies
• Grade 12.9 alloy steel for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Hex socket drive for high-torque installation with a standard hex key
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as an OEM-style and replacement fastener for metric hex socket cap screw applications conforming to DIN 912 and ISO 4762 specifications at M16 x 2.00 sizing.

Installation Notes

Installation requires a correctly sized hex key or socket bit rated for the torque demands of a Grade 12.9 M16 fastener. Ensure the mating threaded bore is clean, undamaged, and of compatible thread pitch before assembly. Do not substitute a lower-grade fastener in applications engineered for Grade 12.9 hardware. Follow applicable equipment manufacturer torque specifications when tightening.
