Electro Hardware 4509-M07-F16 Captive Screw 10-32 Unf

Product Description

The ELECTRO HARDWARE 4509-M07-F16 is a slotted-drive captive screw designed to remain retained in an assembly even when fully backed out. Threaded to the 10-32 UNF standard, it provides a fine-pitch, vibration-resistant fastening point in panels, enclosures, and equipment covers. The screw is machined from 18-8 stainless steel and left uncoated, giving it solid corrosion resistance in both indoor and light-duty outdoor environments. The 27/32-inch length under the head suits moderate panel stack-ups, while the 3/8-inch head diameter and 3/16-inch head height keep the profile low. This fastener is installed by mechanical assemblers, panel fabricators, and field technicians.

The 4509-M07-F16 captive screw is suited for use in electrical enclosures, control panels, HVAC equipment access covers, rack-mount assemblies, and similar applications where losing a fastener during service is not acceptable. Captive screws are common in production and field-service environments where repeated access to internal components is required and loose hardware must be controlled. The slotted drive accommodates standard flat-blade screwdrivers, which are typically available in any field technician toolkit.

Key Features

• Captive design keeps the screw retained in the panel or assembly when backed out
• 10-32 UNF fine-pitch thread for vibration-resistant fastening
• 18-8 stainless steel construction for corrosion resistance
• Uncoated finish - no risk of coating flaking into sensitive assemblies
• Slotted drive - compatible with standard flat-blade screwdrivers
• Meets QQ-S-763 stainless steel material standard

Compatibility

Designed as an OEM-style captive fastener for use in electrical enclosures, control panels, and equipment access covers requiring 10-32 UNF threaded hardware.

Installation Notes

Install and remove using a properly sized flat-blade screwdriver to avoid damaging the slotted head. De-energize and lock out all electrical panels or enclosures before servicing any fasteners on live equipment. Verify that the mating threaded insert or nut plate is clean and undamaged before driving the screw. Do not exceed the torque capacity of the 10-32 thread - stop driving when snug to avoid stripping the stainless fastener or the mating thread.
