Holo-krome 760009940 M36x4 Hex Socket Cap Screw 480mm

Product Description

The HOLO-KROME 760009940 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at M36 x 4.00 with a 480 mm length under head, this fastener is manufactured from alloy steel to material grade 12.9, placing it among the highest strength classifications for metric fasteners. A black oxide coating provides moderate corrosion resistance and reduces surface glare. The hex socket drive accepts a standard Allen or hex key, enabling high-torque installation in tight clearance applications. This screw is compliant with ANSI B1.13M, ISO 4762, and ISO 898-1 standards. Machinists, millwrights, and industrial maintenance technicians are the primary installers of this fastener.

This screw is well suited for heavy-duty mechanical assemblies, machine tool construction, hydraulic equipment mounting, die sets, and structural fixtures where a high-tensile, large-diameter metric fastener is required. The 480 mm length under head makes it appropriate for deep clamping applications or through-bolt configurations in thick material stacks. Its grade 12.9 rating means it is commonly specified by engineers in applications where high preload and fatigue resistance are critical.

Key Features

• Grade 12.9 alloy steel construction for maximum tensile and yield strength
• M36 x 4.00 metric thread size with 480 mm length under head
• Hex socket drive for high-torque installation with standard Allen tooling
• Black oxide finish for moderate corrosion resistance and reduced surface glare
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as a direct-fit metric hex socket cap screw for assemblies requiring an M36 x 4.00 thread profile and conforming to ISO 4762 and ANSI B1.13M dimensional standards.

Installation Notes

Installation should be performed by a qualified machinist or millwright using the appropriate size hex key or Allen socket rated for high-torque applications. Always verify thread engagement depth and mating thread condition before driving the fastener. Lubricate threads as specified by the assembly engineer to achieve accurate preload from applied torque. Power down and de-energize any equipment before performing fastener installation or removal on machinery.
