Value Collection FHS1X02505-050BX M2.5x0.45 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X02505-050BX is an M2.5x0.45 flat socket cap screw manufactured from 18-8 austenitic Grade A2 stainless steel. The 90-degree flat head profile sits flush with the mating surface when properly seated, making it well suited for assemblies where protrusion is not acceptable. Drive engagement is through a 1.50 mm hex socket. The screw is fully threaded along its 5 mm overall length. Machinists, maintenance technicians, and precision assembly workers install this fastener in light mechanical, instrumentation, and equipment applications requiring corrosion-resistant hardware.

This fastener is used in metric-threaded assemblies calling for a countersunk, flush-mount screw with an M2.5x0.45 thread pitch. Typical applications include instrument panels, electronic enclosures, small machinery guards, and precision fixtures where the flat head must sit flush or below the surface. The 18-8 Grade A2 stainless steel construction makes it appropriate for environments with moderate moisture or chemical exposure where carbon steel fasteners would be prone to corrosion. Sold in a minimum order quantity of 50 pieces per order.

Key Features

• 90-degree flat head seats flush with or below the mating surface
• 1.50 mm hex socket drive for precise torque application in tight spaces
• Fully threaded along the entire 5 mm overall length
• 18-8 austenitic Grade A2 stainless steel resists corrosion in moderate-exposure environments
• Conforms to DIN 7991 fastener standard
• Metric thread standard, M2.5x0.45 pitch

Compatibility

Designed for use in metric-threaded applications requiring an M2.5x0.45 DIN 7991 flat socket cap screw in 18-8 Grade A2 stainless steel.

Installation Notes

Install using a calibrated 1.50 mm hex key or hex socket bit to avoid stripping the drive recess. Ensure the mating hole is countersunk to 90 degrees for proper flush seating. Clean threads and verify thread engagement before final torque. Avoid mixing with non-stainless hardware in corrosive environments to prevent galvanic issues.
