Value Collection FHS1X0435-100BX M4x0.7 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0435-100BX is a metric flat socket cap screw designed for flush or countersunk fastening applications in industrial, mechanical, and fabrication settings. It features an M4x0.7 thread size, a 35 mm overall length, and a 90-degree flat head with a 2.50 mm hex socket drive. The fastener is constructed from 18-8 austenitic stainless steel to Grade A2, providing solid corrosion resistance in environments exposed to moisture, mild chemicals, or outdoor conditions. Partial threading allows for controlled clamping and is appropriate for through-bolt and threaded-insert installations. This screw meets DIN 7991 dimensional standards and is suited for assembly technicians, machinists, and maintenance professionals.

This flat socket cap screw is used in applications where a low-profile, countersunk head is required to sit flush with or below the mating surface. Typical installations include machine frames, enclosures, jigs, fixtures, sheet metal assemblies, and precision equipment. The hex socket drive allows torque application in confined spaces where standard hex or Phillips drivers cannot reach. The Grade A2 stainless steel construction makes it appropriate for light marine, food-adjacent, or outdoor service environments where mild corrosion resistance is required.

Compatibility

Designed as a metric replacement or standard-use flat socket cap screw for applications conforming to DIN 7991 specifications with M4x0.7 thread engagement.

Installation Notes

Installation should be performed by a qualified assembly technician or machinist using a correctly sized 2.50 mm hex key or socket bit. Ensure the mating countersink angle matches the 90-degree head profile before driving the fastener. Do not overtorque stainless steel fasteners, as galling can occur; apply an anti-seize compound when assembling stainless-to-stainless interfaces. Verify thread engagement depth meets the requirements of the host material before final assembly.
