Value Collection MAFS0050020CP M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION MAFS0050020CP is a metric flat socket cap screw designed for flush or countersunk fastening applications in industrial, mechanical, and structural assemblies. It features a 90-degree flat head with a 3.00 mm hex socket drive, allowing installation with a standard hex key into countersunk holes where a low-profile surface finish is required. The screw is fully threaded along its 20.00 mm overall length, conforming to DIN 7991. Constructed from 18-8 stainless steel, it provides solid corrosion resistance for general-purpose indoor and outdoor use. Licensed mechanics, machinists, and maintenance technicians are the primary installers.

This screw is suited for equipment assembly, machine frames, panel mounting, and fixture fabrication where a flush fastener profile is necessary. The M5x0.8 thread size and metric dimensioning make it a standard fit in metric-spec equipment across manufacturing, HVAC fabrication, and general industrial maintenance. The fully threaded shank provides consistent clamping force throughout the engaged thread length, making it effective in thin-material applications and blind-hole assemblies.

Key Features

• 90-degree flat head seats flush in standard countersunk holes
• 3.00 mm hex socket drive for precise torque application with a hex key
• M5x0.8 metric thread with 20.00 mm overall length, fully threaded
• 18-8 stainless steel construction for corrosion resistance
• Conforms to DIN 7991 fastener standard
• Metric thread standard for compatibility with metric-spec assemblies

Compatibility

Designed as an OEM-style metric fastener for use in any application requiring a DIN 7991 M5x0.8 flat socket cap screw with a 90-degree countersunk head.

Installation Notes

Installation requires a 3.00 mm hex key or hex bit driver. Ensure the receiving hole is countersunk to a matching 90-degree angle before driving the screw. Avoid over-torquing stainless steel fasteners, as galling can occur when threading into stainless or aluminum tapped holes. Use of an appropriate thread lubricant or anti-seize compound is recommended to reduce the risk of galling during installation.
