Value Collection FHS1X0425-050BX M4x0.7 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0425-050BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head driven by a hex socket and is partially threaded along its shank. Built from 18-8 austenitic stainless steel to Grade A2, this screw resists corrosion in wet, chemical, and outdoor environments. The M4x0.7 thread pitch and 25 mm overall length make it a common choice for precision assemblies, machine components, and light structural connections where a low-profile head is required. This fastener conforms to DIN 7991 standards.

This screw is suited for use in mechanical assemblies, electrical enclosures, panel fabrication, HVAC equipment housings, pump and valve bodies, and general trade fabrication work. The countersunk head seats flush with the mating surface, making it appropriate for installations where protrusion would interfere with adjacent components or moving parts. It is handled by machinists, millwrights, HVAC technicians, plumbers, and electricians during equipment assembly and repair work. The minimum order quantity is 50 pieces per order.

Key Features

• 90-degree flat countersunk head sits flush with mating surface
• Hex socket drive for precise torque application with Allen or hex key tooling
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in wet and industrial environments
• Partially threaded shank per DIN 7991 standard
• M4x0.7 metric thread size with 25 mm overall length
• Minimum order quantity of 50 pieces per box

Compatibility

Designed as a DIN 7991 compliant metric flat socket cap screw for use in any application requiring an M4x0.7 countersunk hex socket fastener in stainless steel.

Installation Notes

Install using the appropriate 2.50 mm hex key or Allen driver to ensure proper seating without stripping the socket. Countersink the mating hole to 90 degrees before installation to achieve a flush head seating surface. Do not overtorque stainless steel fasteners, as the material is susceptible to galling — apply an anti-seize compound where thread galling is a concern. Power down or de-energize any equipment before accessing fastened panels or enclosures.
