Value Collection 534070PR Flat Socket Cap Screw M2.5x0.45

Product Description

The VALUE COLLECTION 534070PR is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastener with a hex socket drive. Manufactured from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in controlled environments. The 90-degree flat head seats flush with or below the mating surface when installed into a properly countersunk hole. Thread size is M2.5x0.45 with an overall length of 16 millimeters. The fastener is fully threaded along its entire shaft length, making it well suited for thin material assemblies and precision mechanical work.

This flat socket cap screw is used in light industrial, mechanical, and precision assembly applications where a recessed hex drive and flush head profile are required. Common installation scenarios include machine guarding, electronic enclosures, instrumentation housings, and jigs or fixtures where protruding fastener heads are not acceptable. The fully threaded design provides maximum thread engagement in thinner stock. Installers working in metric-standard assemblies will find this screw compatible with standard M2.5 tapped holes.

Key Features

• 90-degree flat head seats flush when installed in a properly countersunk hole
• Hex socket drive for precise torque application with standard hex keys or bit drivers
• Alloy steel construction provides strong tensile and shear resistance
• Black oxide finish offers mild corrosion protection and reduces light reflection
• Fully threaded shaft maximizes thread engagement in thin materials
• Metric M2.5x0.45 thread standard for use in metric-dimensioned assemblies

Compatibility

Designed as a standard metric replacement or maintenance fastener for assemblies using M2.5x0.45 threaded holes with countersunk seat geometry.

Installation Notes

Installation is typically performed by a machinist, millwright, or mechanical technician using a correctly sized hex key or socket bit. The mating hole must be countersunk to 90 degrees to achieve proper flush seating of the flat head. Do not overdrive the fastener into the countersink, as this can strip the thread or crack the material around the hole. Ensure all mating surfaces are clean and free of debris before fastening.
