Electro Hardware 4102M07F16 Captive Screw 4-40 Unc

Product Description

The ELECTRO HARDWARE 4102M07F16 is a slotted-drive captive screw designed to stay retained in an assembly panel or mating component rather than fall free during servicing. Threaded to the 4-40 UNC standard, it features a 23/32-inch length under head, a 5/16-inch head diameter, and a 3/16-inch head height. The fastener is manufactured from 18-8 stainless steel left in an uncoated finish, offering reliable corrosion resistance in environments where mild chemical or moisture exposure is a concern. Captive screws are a preferred hardware choice wherever tool-free or single-hand panel removal is required, reducing dropped hardware and speeding up field service cycles.

This captive screw is suited for use in electrical enclosures, control panels, HVAC equipment access covers, and similar assemblies where a retained fastener prevents hardware loss during routine inspection or maintenance. The slotted drive accommodates a standard flat-head screwdriver, making it accessible in tight spaces where a power driver may not fit. It is appropriate for both light commercial and residential equipment applications where 4-40 UNC threaded hardware is specified.

Key Features

• Captive design keeps screw retained during panel removal, reducing dropped-fastener risk
• 4-40 UNC thread standard for compatibility with common threaded inserts and panels
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Slotted drive works with standard flat-head screwdrivers in confined spaces
• 23/32-inch length under head suits typical thin-panel and access-cover applications
• Meets QQ-S-763 stainless steel material standard

Compatibility

Designed as a retained-fastener replacement for assemblies calling for a 4-40 UNC slotted captive screw with a 23/32-inch length under head in 18-8 stainless steel.

Installation Notes

Installation is performed by a qualified technician or assembler using a flat-head screwdriver sized to the slotted head. Power down all associated equipment before removing or replacing panel fasteners in live electrical enclosures, in accordance with applicable NFPA 70 lockout/tagout requirements. Verify thread engagement depth against the mating component specification before final torque to avoid cross-threading the 4-40 UNC threads. Minimum order quantity is 10 units.
