Value Collection SCXX204025-050BX M4 Socket Cap Screw 50-pack

Product Description

The VALUE COLLECTION SCXX204025-050BX is a metric hex socket cap screw designed for precision fastening applications in industrial, mechanical, and structural assemblies. This screw features an M4 x 0.70 thread pitch and a 25 mm length under head with partial threading. Manufactured from 316 stainless steel to Austenitic Grade A4, it delivers strong corrosion resistance in wet, marine, and chemical-exposure environments. The internal hex drive accepts a standard hex key for installation in tight or recessed spaces. Sold in a minimum quantity of 50 pieces per order, making it suitable for production and maintenance stock.

This fastener is commonly used by machinists, mechanical contractors, and maintenance technicians in applications where corrosion resistance and dimensional accuracy are required. Typical use cases include equipment frames, enclosures, fluid handling assemblies, and marine hardware. The DIN 912 standard ensures consistent head geometry, thread form, and mechanical properties across the lot. Grade A4 316 stainless steel is well-suited for outdoor, saltwater, and chemically aggressive service conditions where standard carbon or 304 stainless fasteners may fall short.

Key Features

• M4 x 0.70 thread with 25 mm length under head for precise metric fastening
• Partial threading for clamping force in through-hole and clearance-hole applications
• 316 stainless steel, Austenitic Grade A4 for superior corrosion resistance
• Internal hex socket drive compatible with standard hex keys and hex bit drivers
• Bright uncoated finish — no coating thickness to account for in tolerance-critical fits
• Conforms to DIN 912 fastener standard for consistent geometry and performance

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M4-threaded assemblies requiring Grade A4 316 stainless steel fasteners.

Installation Notes

Installation should be performed with the correct metric hex key or hex bit to avoid drive recess damage. Confirm mating thread condition and apply appropriate thread engagement depth before torquing. In stainless-to-stainless applications, use an anti-galling compound to reduce the risk of thread seizure. Always follow applicable mechanical or structural codes for fastener torque and joint design requirements.
