Value Collection 534034PR M4x0.7 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534034PR is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built to DIN 7991 standard, it features a 90-degree flat head with a 2.5 mm hex socket drive and is manufactured from 12.9 grade alloy steel with a black oxide finish. The 12.9 material grade indicates a high-strength fastener suitable for demanding mechanical assemblies. The black oxide coating provides a low-reflectance appearance and minimal corrosion resistance in dry or lightly oiled environments. This screw is partially threaded with an M4x0.7 thread and an overall length of 30 mm. It is typically installed by machinists, millwrights, equipment technicians, and maintenance professionals working on precision assemblies.

This fastener is well suited for machine tool components, fixtures, jigs, and mechanical assemblies where a flush head profile is required and bolt head protrusion would interfere with mating surfaces or clearance envelopes. The M4x0.7 metric thread and DIN 7991 compliance make it a standard choice for European-spec equipment and metric-dimensioned fabrications in both industrial and light commercial settings. Minimum order quantity is 100 pieces per order.

Key Features

• DIN 7991 standard 90-degree flat head for flush countersunk installations
• 12.9 alloy steel construction provides high tensile and proof load strength
• 2.5 mm hex socket drive for precise torque application with standard hex keys
• Black oxide finish for a low-profile, dark appearance with light corrosion resistance
• Partial threading along M4x0.7 shank for controlled engagement depth
• Metric thread standard for compatibility with metric-dimensioned components

Compatibility

Designed as a standard DIN 7991 metric flat socket cap screw compatible with M4x0.7 threaded bores in metric-dimensioned machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation is performed using a 2.5 mm hex key or T-handle driver. Ensure the mating bore is properly countersunk to 90 degrees to achieve full head seating. Power down or de-energize any associated equipment before disassembly or fastener replacement. Do not reuse fasteners in critical joints where the original torque specification required a one-time-use designation.
