Value Collection FHS1XX0508-050BX Flat Socket Cap Screw M5x0.8

Product Description

The VALUE COLLECTION FHS1XX0508-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications in corrosion-sensitive environments. It features an M5x0.8 thread size and an overall length of 8 millimeters, with full threading along the shank. The 90-degree flat head seats flush with the mating surface when installed in a properly chamfered hole. Drive engagement is through a 3.00 millimeter hex socket. Constructed from 316 stainless steel to Austenitic Grade A4, it resists corrosion from moisture, chemicals, and marine exposure. This screw is installed by machinists, maintenance technicians, and fabricators across industrial, marine, and commercial equipment applications.

This flat socket cap screw is suited for use in assemblies where a low-profile, flush-mount fastener is required and corrosion resistance is a priority. Typical applications include marine hardware, food processing equipment, chemical processing assemblies, and stainless fabrication work. The M5x0.8 metric thread pattern and DIN 7991 standard make it a common fit for OEM equipment built to metric specifications. It is sold in multiples of 50 units per order.

Key Features

• 90-degree flat head profile allows flush seating in countersunk holes
• 3.00 millimeter hex socket drive for standard Allen key or hex bit installation
• 316 stainless steel construction, Austenitic Grade A4, for high corrosion resistance
• Fully threaded shank along the entire 8 millimeter length
• Conforms to DIN 7991 fastener standard
• Metric thread standard, M5x0.8 pitch

Compatibility

Designed as a metric DIN 7991 flat socket cap screw for use in countersunk applications requiring M5x0.8 thread engagement and Grade A4 stainless steel corrosion resistance.

Installation Notes

Installation requires a properly sized countersunk or chamfered hole to achieve full flush seating of the flat head. Use a calibrated 3.00 millimeter hex key or hex socket bit to apply torque. De-energize and lock out any equipment before fastener service per applicable safety procedures. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or galvanically active environments to minimize corrosion risk.
