Value Collection SCX203030-050BX M3 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION SCX203030-050BX is a metric hex socket cap screw designed for precision fastening applications in mechanical assemblies, equipment manufacturing, and maintenance work. Sized at M3 x 0.50 with a 30 mm length under head, this screw features a partially threaded shank and a hex socket drive for positive torque engagement. Constructed from 18-8 austenitic stainless steel (Grade A2), it provides corrosion resistance suitable for indoor and outdoor environments. Sold in a minimum order box of 50 pieces, this fastener conforms to DIN 912 standards and arrives in a bright, uncoated finish. Licensed trades and precision assembly technicians are the primary installers.

This screw suits a wide range of light mechanical assemblies where a small-diameter metric fastener is required. Common applications include equipment enclosures, panel mounting, pump components, HVAC control cabinet hardware, and general machine assembly where M3 fastener sizing is specified. The partially threaded shank provides clamping force between joined components, making it appropriate where thread engagement is needed only at the mating surface rather than the full shank length. The DIN 912 standard ensures dimensional consistency for use in applications specifying that fastener form factor.

Key Features

• M3 x 0.50 thread size with 30 mm length under head per DIN 912 standard
• Partially threaded shank for controlled clamping in bolted joints
• 18-8 austenitic stainless steel, Grade A2 for corrosion resistance
• Hex socket drive accepts standard hex keys and driver bits for positive engagement
• Bright uncoated finish — no coating thickness to account for in tolerance-sensitive fits
• Packaged in a box of 50 pieces for bench stock and production use

Compatibility

Designed for use in any application calling for a DIN 912 hex socket cap screw in M3 x 0.50 thread with a 30 mm length under head and partial threading. Fits standard M3 threaded inserts, tapped holes, and hex key sets sized for M3 socket cap screws.

Installation Notes

Installation is performed with a standard 2.5 mm hex key or hex bit driver. Ensure the mating threaded hole or insert is clean and free of debris before driving. Do not exceed the rated torque range for M3 stainless fasteners to avoid galling, which is a common failure mode with austenitic stainless hardware. Apply an anti-seize compound if repeated removal is anticipated in stainless-to-stainless assemblies.
