Holo-krome 76946 Hex Socket Cap Screw M36 X 4.00 Alloy Steel

Product Description

The HOLO-KROME 76946 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It carries an M36 x 4.00 thread size with a 240 mm (approximately 9.45 inches) length under head. Manufactured from alloy steel to material grade 12.9 and finished with a black oxide coating, this fastener delivers exceptional tensile strength and moderate corrosion resistance. The internal hex drive requires a hex key for installation and allows high torque application in tight-clearance situations. Licensed machinists, millwrights, maintenance technicians, and industrial assemblers are the typical installers.

This fastener is suited for heavy-duty bolted joints in machinery, hydraulic equipment, tooling fixtures, die sets, and structural steel fabrication where high-strength metric fasteners are specified. The 12.9 material grade indicates a proof load and tensile strength class appropriate for critical load-bearing connections. Conformance to ANSI B1.13M, ISO 4762, and ISO 898-1 standards makes this screw compatible with metric design specifications used in both domestic and international engineering applications.

Compatibility

Designed as an OEM-style metric hex socket cap screw for applications specifying M36 x 4.00 thread pitch and conforming to ISO 4762 socket head cap screw geometry and ISO 898-1 mechanical property requirements.

Installation Notes

Installation requires a properly sized metric hex key or socket driver rated for the torque demands of a grade 12.9 fastener. Verify that mating threaded holes are cut to M36 x 4.00 pitch before installation to avoid cross-threading. De-energize or shut down any equipment being serviced before fastener removal or installation. Follow applicable equipment manufacturer torque specifications and any governing mechanical codes for the installation environment.
