Value Collection 534088PR Flat Socket Cap Screw M6x1

Product Description

The VALUE COLLECTION 534088PR is a metric flat socket cap screw designed for applications requiring a flush or countersunk head profile. Built to DIN 7991 standard, it features a 90-degree flat head with a hex socket drive and is manufactured from 12.9 grade alloy steel — the highest common strength grade for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. This fastener is partially threaded, with an M6x1 thread size and an overall length of 40 millimeters. Machinists, tool and die technicians, and mechanical assemblers install this type of screw where a low-profile head is required.

This flat socket cap screw is suited for use in precision mechanical assemblies, jigs, fixtures, machine tools, and industrial equipment where the head must sit flush with or below the mating surface. The countersunk seating angle is 90 degrees, compatible with standard metric countersunk hole preparations per DIN 7991. It is partially threaded, which helps resist loosening under shear loads and provides clearance-hole clamping in bolted joint designs. Typical users include CNC machine builders, toolmakers, and maintenance technicians working on metric-specification equipment.

Key Features

• 12.9 grade alloy steel construction for high tensile and shear strength in demanding fastener applications
• 90-degree flat countersunk head seats flush with the mating surface for low-profile, unobstructed assemblies
• Hex socket (Allen) drive for high torque input in confined spaces
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Partially threaded shank provides accurate clamping and resistance to lateral shear forces
• Manufactured to DIN 7991 fastener standard for dimensional consistency and interchangeability

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for standard M6 countersunk hole patterns in industrial machinery, fixtures, and precision mechanical assemblies.

Installation Notes

Installation requires a 4 millimeter hex key or socket driver sized to the hex socket drive. Ensure the countersunk hole is machined to the correct 90-degree included angle and appropriate depth before installation. Torque to the value specified by the assembly designer for 12.9 grade fasteners at M6 size — do not rely on generic values without verifying joint design requirements. As with all high-strength fasteners, avoid reuse after yield or after removal from a torque-to-yield joint.
