Holo-krome 87077 Flat Socket Cap Screw M5x0.8 35mm

Product Description

The HOLO-KROME 87077 is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. It features a 90-degree flat head driven by a 3.00 mm hex socket, and is fully threaded along its 35.00 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. The M5x0.8 thread size and 4G thread fit class make it suitable for precision metric assemblies where close-tolerance fastening is required. Licensed HVAC, plumbing, mechanical, and industrial technicians commonly install this hardware in equipment panels, brackets, and structural components.

This flat socket cap screw is used in residential and commercial mechanical installations where a low-profile, flush-mount fastener is needed. The 90-degree countersunk head seats flush with the mating surface, keeping assemblies compact and reducing snag points. It conforms to ANSI B1.13M and ISO 10642 fastener standards, making it appropriate for applications where dimensional and mechanical compliance with metric fastener specifications is required. It is sold in minimum order quantities of 10 units per order.

Key Features

• 90-degree flat head with 3.00 mm hex socket drive for flush countersunk installation
• M5x0.8 thread size, fully threaded along 35.00 mm overall length

Compatibility

Designed as a metric replacement or service fastener conforming to ANSI B1.13M and ISO 10642 standards, suitable for use in any application calling for an M5x0.8 flat socket cap screw with a 90-degree head profile.

Installation Notes

Install using a calibrated 3.00 mm hex key or hex socket driver. Ensure the mating component has a properly machined 90-degree countersink before seating the screw. Power down or de-energize any equipment before replacing fasteners in live mechanical or electrical assemblies. Follow applicable mechanical codes and torque specifications provided by the equipment manufacturer.
