Value Collection HC3X03012-050BX Hex Cap Screw M3 50pk

Product Description

The VALUE COLLECTION HC3X03012-050BX is a fully threaded metric hex head cap screw used to fasten components in mechanical assemblies across HVAC, plumbing, electrical, and general trade applications. It is manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish, providing solid corrosion resistance in moderate-exposure environments. The screw measures M3 x 0.50 thread pitch with a 12 mm length under the head and a 5.5 mm hex drive. It conforms to DIN 933 standards. This package contains 50 pieces, making it a practical restocking unit for service vans, shop bins, or job-site kits.

This screw is suited for metric fastening tasks in residential and light commercial trade work. Common applications include securing control board mounting brackets, enclosure covers, panel components, and equipment housings where corrosion resistance and dimensional precision matter. The M3 size is frequently used in electrical enclosures, HVAC control assemblies, and small mechanical sub-assemblies. The fully threaded shank allows full thread engagement across the entire clamped length, which is preferred in thin-material and close-tolerance installations.

Key Features

• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance
• Fully threaded shank per DIN 933 standard for maximum thread engagement
• M3 x 0.50 metric thread with 12 mm length under head
• 5.5 mm hex drive accepts standard metric hex wrenches and sockets
• Bright, uncoated finish — no plating to flake or degrade over time
• Pack of 50 units for efficient bin stocking and bulk service use

Compatibility

Designed for use in any application requiring a DIN 933 fully threaded metric hex head cap screw in M3 x 0.50 thread size, compatible with standard M3 metric hex nuts and threaded inserts.

Installation Notes

Installation is performed with a 5.5 mm hex wrench or socket. Ensure mating threads are clean and free of debris before driving to avoid cross-threading the small-diameter M3 thread. Do not exceed recommended torque for M3 stainless fasteners, as 18-8 stainless is susceptible to galling under high rotational load — applying an anti-seize compound to threads is common practice. Confirm thread pitch compatibility with the receiving nut or tapped hole before installation.
