Value Collection -43137-1 M5x0.8 Flat Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION -43137-1 is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies, tooling, fixtures, and equipment. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance in a low-profile, countersunk head profile. The 3.00 mm hex socket drive accepts a standard Allen key. The fully threaded M5x0.8 shank at 14.00 mm overall length meets DIN 7991 standards. This item is sold as a pack of 25 pieces.

This screw is suited for applications where the fastener head must sit flush or below the mating surface, such as panel mounting, precision machinery, CNC fixtures, and structural brackets. The 90-degree flat head angle is consistent with standard countersunk hole geometry. Licensed machinists, millwrights, tool and die makers, and maintenance technicians commonly install this fastener in both production and field-service settings.

Key Features

• DIN 7991 standard flat socket cap screw for metric countersunk applications
• 12.9 grade alloy steel construction for high tensile and proof load capacity
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 90-degree flat head seats flush in standard countersunk holes
• 3.00 mm hex socket drive for Allen key installation with controlled torque
• Fully threaded M5x0.8 shank for maximum thread engagement in thin materials

Compatibility

Designed as an OEM-style replacement or standard metric fastener for countersunk applications requiring an M5x0.8 thread pitch and DIN 7991 geometry.

Installation Notes

Install using a calibrated hex key or socket bit sized to 3.00 mm. Ensure the mating material is drilled and countersunk to 90-degree geometry before installation. Power down or de-energize any equipment before performing fastener service in electrical or mechanical enclosures. Follow applicable torque specifications published in relevant engineering standards for 12.9 grade M5 fasteners.
