Value Collection 3TSCS04C006 Hex Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION 3TSCS04C006 is a 4-40 UNC hex socket cap screw designed for precision fastening in mechanical assemblies, enclosures, and equipment where a low-profile, high-strength fastener is required. Constructed from 316 stainless steel, this screw resists corrosion in wet, chemical-exposed, or marine environments. The 5/32 inch hex drive accepts a standard ball-end or straight hex key, and the 3/8 inch length under head suits shallow-clearance applications. Technicians and tradespeople who work with small-bore threaded assemblies will find this an accurate OEM-style replacement or new-installation fastener for 4-40 tapped holes.

This screw is suited for use in HVAC control panel assemblies, electrical enclosures, pump housings, instrumentation brackets, and similar light-duty mechanical connections where a 4-40 UNC thread pattern is specified. The 316 stainless steel material grade makes it appropriate for outdoor, poolside, coastal, or chemically aggressive environments where carbon steel fasteners would corrode prematurely. It is ordered and sold in minimum quantities of 50 pieces per order increment, with each package containing 1 unit as cataloged.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• 4-40 UNC thread size for compatibility with standard small-bore tapped holes
• 5/32 inch hex socket drive accepts standard hex keys and ball-end drivers
• 3/8 inch length under head suits shallow-clearance and panel-mount applications
• Low-profile socket cap head keeps a clean, flush appearance in finished assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fastener for any assembly specifying a 4-40 UNC hex socket cap screw with a 3/8 inch length under head and a 5/32 inch hex drive.

Installation Notes

Installation requires a 5/32 inch hex key or ball-end driver. Power down and de-energize any electrical panel or enclosure before inserting or removing fasteners in live equipment. Avoid overtightening into tapped aluminum or plastic bosses, as 4-40 threads are fine-pitch and susceptible to stripping under excess torque. Follow applicable NEC or equipment manufacturer guidelines when securing components inside electrical enclosures.
