Metric Blue UST194860 M3x0.50 Button Cap Screw 8mm

Product Description

The METRIC BLUE UST194860 is a fully threaded M3x0.50 button socket cap screw designed for precision fastening in metal assemblies, machinery, and equipment. This screw meets ISO 7380 standards and is manufactured from Grade 10.9 alloy steel with a blue phosphate finish. The low-profile button head provides a rounded, flush-friendly profile well suited for applications where clearance is limited or a smooth external surface is required. At 8mm length under head and driven by a 2mm hex socket, it delivers the clamping force expected from a high-strength metric fastener.

This fastener is used in light industrial, mechanical, and fabrication applications requiring a compact, high-strength metric screw. It is commonly installed in machine frames, enclosures, brackets, and precision assemblies where an M3 thread pitch and a low-profile head are specified. The Grade 10.9 rating makes it appropriate for moderate to high load applications. It is ordered in multiples of 100 units per package.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in compact fastener format
• ISO 7380 fastener standard compliance ensures dimensional consistency
• Blue phosphate finish provides corrosion resistance and identification in metric fastener assortments
• Button head profile minimizes protrusion and suits flush or near-flush installations
• 2mm hex socket drive for precise torque application in tight clearance areas
• Fully threaded shank along the 8mm under-head length for maximum thread engagement

Compatibility

Designed for use in applications specifying an M3x0.50 metric thread pitch and ISO 7380 button socket cap screw geometry. Suitable for alloy steel fastener installations in mechanical assemblies, enclosures, and fabricated components requiring a Grade 10.9 fastener.

Installation Notes

Install using a 2mm hex socket driver or ball-end hex key; confirm the driver is fully seated before applying torque to avoid cam-out and head damage. Follow applicable mechanical assembly specifications or equipment OEM torque tables for M3 Grade 10.9 hardware. Inspect mating threads for cleanliness and proper thread form before installation. Minimum order quantity is 100 pieces per order.
