Value Collection KP82388 M4x0.7 Flat Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION KP82388 is a metric flat socket cap screw designed for flush or countersunk fastening applications requiring corrosion-resistant hardware. Built to DIN 7991 standard, it features a 90-degree flat head driven by a 2.50 mm hex socket. The screw is fabricated from 18-8 austenitic stainless steel, Grade A2, offering solid resistance to rust and oxidation in wet or chemically active environments. The M4x0.7 thread with 25 mm overall length and partial threading makes it suitable for controlled-depth clamping in metal, plastic, or composite assemblies. This package contains 25 pieces, making it appropriate for service stock or job-lot replenishment by maintenance technicians and trade mechanics.

This screw is used wherever a low-profile, countersunk fastener is required in metric assemblies. Typical applications include electrical enclosure panels, HVAC equipment housings, pump brackets, plumbing fixture components, and general mechanical assemblies where the fastener head must sit flush or below the surface. The stainless steel construction makes it especially practical in humid, outdoor, or poolside environments where carbon steel hardware would corrode prematurely.

Key Features

• 90-degree flat head profile allows flush or countersunk installation
• 2.50 mm hex socket drive for precise torque application with standard Allen keys
• M4x0.7 metric thread per DIN 7991 fastener standard
• 18-8 austenitic stainless steel, Grade A2 for corrosion resistance
• Partially threaded shank for controlled clamping in varying material thicknesses
• Sold in a 25-piece package for convenient service or shop stock

Compatibility

Designed as a DIN 7991 metric flat socket cap screw in M4x0.7 thread size, compatible with standard M4 metric countersunk holes in equipment housings, panels, and mechanical assemblies requiring a flush-head fastener.

Installation Notes

Installation requires a 2.50 mm hex key or Allen driver; use a torque wrench where specification sheets call for controlled clamping force. Ensure the receiving hole is properly countersunk to 90 degrees before driving to avoid head damage or surface distortion. De-energize any equipment before accessing internal fasteners on electrical or HVAC components. Stainless fasteners can be prone to galling under high torque -- apply anti-seize compound to threads when assembling stainless into stainless hardware.
