Value Collection 43146 M6x1 Flat Socket Cap Screw 12.9 Alloy Steel

Product Description

The VALUE COLLECTION 43146 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built to DIN 7991 standard, it features a 90-degree flat head with a 4 mm hex socket drive and is fully threaded along its 16 mm overall length. The M6x1 thread pitch and 12.9 material grade alloy steel construction make this screw suitable for high-strength clamping in tight or recessed installations. The black oxide finish provides a degree of corrosion resistance and a uniform dark appearance. Installers in mechanical, industrial, and light fabrication trades reach for this fastener when a standard button or pan head would protrude above the mating surface.

This flat socket cap screw is commonly used in machine assemblies, tooling fixtures, and equipment panels where a low-profile fastener is required. The 90-degree flat head seats into a countersunk hole, drawing flush with or below the surrounding surface. Fully threaded construction allows engagement across the full fastener length, which is advantageous in thinner material stacks or through-bolt configurations. This screw is sold individually, with a minimum order quantity of 25 pieces.

Key Features

• DIN 7991 standard flat socket cap screw with 90-degree countersunk head
• M6x1 metric thread, fully threaded along the entire 16 mm length
• 4 mm hex socket drive for Allen key or hex bit installation
• 12.9 grade alloy steel for high tensile and proof load strength
• Black oxide finish for corrosion resistance and low-reflectance appearance

Compatibility

Designed as a metric replacement or service fastener for any application requiring a DIN 7991 M6x1 fully threaded flat socket cap screw with a 12.9 material grade and black oxide finish.

Installation Notes

Installation requires a 4 mm hex key or hex socket bit. Ensure the mating hole is countersunk to 90 degrees to achieve proper head seating. Power down or de-energize any equipment before disassembly and fastener replacement. Do not mix metric and imperial fasteners in the same threaded hole, as thread form mismatch will damage the thread engagement.
