Value Collection 534066PR M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534066PR is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. Machined from alloy steel with a black oxide finish, this screw features a 90-degree flat head profile and a hex socket drive for precise torque application in confined or recessed spaces. The M5x0.8 thread size with a 45 mm overall length accommodates a wide range of medium-duty structural and mechanical connections. Partial threading along the shank provides a grip zone suited to bolted joints where clamping load distribution matters. Installation is performed with a standard hex key or Allen driver.

This fastener suits industrial, machinery, and equipment assembly applications where a low-profile or flush-mount head is required. The black oxide finish offers moderate corrosion resistance suitable for indoor or protected environments. The metric thread standard makes this screw compatible with metric-dimensioned components across manufacturing, fabrication, and MRO maintenance workflows. Machinists, millwrights, and maintenance technicians commonly use this fastener type when assembling jigs, fixtures, panels, and enclosures.

Key Features

• 90-degree flat head profile for flush or countersunk seating
• Hex socket drive allows high torque in recessed or tight clearance locations
• M5x0.8 metric thread for compatibility with standard metric components
• Partial threading along shank for controlled clamping load distribution
• Black oxide finish provides moderate corrosion resistance in protected environments
• Alloy steel construction for strength in medium-duty mechanical applications

Compatibility

Designed as a metric-standard flat socket cap screw for use in any M5x0.8 tapped hole requiring a 90-degree countersunk head seating profile.

Installation Notes

Install using a correctly sized hex key or Allen driver to avoid cam-out and socket damage. Ensure the mating countersunk hole is machined to a 90-degree included angle before seating the fastener. Apply thread-locking compound or washers as required by the assembly specification. Follow applicable fastener torque standards for M5 alloy steel hardware per the relevant industry or equipment documentation.
