Value Collection SCXX203012-050BX M3 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION SCXX203012-050BX is a fully threaded hex socket cap screw designed for precision fastening applications requiring metric sizing and corrosion resistance. This screw features an M3 x 0.50 thread size with a 12 mm length under head and is driven by an internal hex socket, making it compatible with standard Allen keys and hex drivers. Manufactured from 316 stainless steel to the Austenitic Grade A4 classification and conforming to DIN 912, this fastener is well suited for environments where moisture, chemicals, or salt exposure are concerns. It ships in a minimum order quantity of 50 pieces per package.

This fastener is used across a wide range of light mechanical assemblies, instrumentation panels, HVAC equipment housings, electrical enclosures, and plumbing fixture components where small-diameter metric fasteners are required. The M3 sizing is common in control boards, motor brackets, panel mounting, and component assembly in both residential and commercial trade work. The Grade A4 316 stainless steel construction makes it appropriate for outdoor, wet, or chemically exposed installations where carbon steel or lower-grade stainless fasteners would corrode prematurely.

Key Features

• M3 x 0.50 thread with 12 mm length under head for precise metric fitment
• Fully threaded shank provides maximum thread engagement across the full grip length
• 316 stainless steel, Austenitic Grade A4 for superior corrosion resistance
• Bright uncoated finish maintains dimensional accuracy and allows direct metal-to-metal contact
• Conforms to DIN 912 standard for consistent head geometry and drive socket dimensions
• Internal hex socket drive reduces cam-out risk during installation

Compatibility

Designed as a DIN 912 metric hex socket cap screw suitable for M3 threaded holes with a 0.50 mm pitch. Fits standard M3 clearance and tapped holes across equipment panels, enclosures, and mechanical assemblies that require a metric fastener to this thread specification.

Installation Notes

Installation is typically performed by maintenance technicians, electricians, or mechanical tradespeople using a metric hex key or Allen driver sized for M3 socket cap screws. Always verify thread pitch and hole depth before installation to avoid cross-threading or bottoming out. Torque to the equipment or assembly specification provided by the original equipment manufacturer. When installing into dissimilar metals in wet environments, consider anti-seize or isolation hardware to prevent galvanic corrosion.
