Value Collection SCX203018-100BX M3x0.50 Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION SCX203018-100BX is a metric hex socket cap screw designed for precision fastening applications where a clean, low-profile head and positive socket drive are required. Built to DIN 912 standards, this screw features an M3 x 0.50 thread pitch and an 18 mm length under head. The fully threaded shank allows maximum thread engagement in thin materials or shallow tapped holes. Constructed from 18-8 stainless steel (Austenitic Grade A2), it resists corrosion in wet or chemical-exposure environments. Each box contains 100 pieces, making it practical for production, maintenance, or field service use.

This fastener is suited for light mechanical assemblies, electronic enclosures, instrumentation panels, HVAC control mounting, plumbing fixture components, and general-purpose machine work where an M3 metric thread is specified. The hex socket drive accepts a standard 2.5 mm hex key or Allen wrench, allowing torque application in confined spaces where external-drive tools cannot reach. Stainless steel construction makes it appropriate for both indoor and outdoor installations where mild corrosion resistance is needed.

Key Features

• M3 x 0.50 thread size per DIN 912 fastener standard
• 18 mm length under head, fully threaded shank for maximum thread engagement
• 18-8 stainless steel, Austenitic Grade A2 for corrosion resistance
• Hex socket (Allen) drive for use in tight or recessed spaces
• Sold in a 100-piece box to support production and service quantities

Compatibility

Designed as a standard DIN 912 metric socket cap screw for any application requiring an M3 x 0.50 thread; fits any tapped hole or nut conforming to that metric specification.

Installation Notes

Install with a 2.5 mm hex key or socket driver sized for M3 fasteners. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid galling, which can occur with stainless-to-stainless contact. Apply an appropriate anti-seize compound if the fastener will be installed into a stainless or aluminum tapped hole. Follow applicable mechanical or structural codes for the specific assembly being serviced.
