Value Collection R63091221 Machine Screw 10-32 Binding Head

Product Description

The VALUE COLLECTION R63091221 is a 10-32 UNF machine screw designed for general-purpose fastening in electrical, HVAC, and light mechanical assemblies. The binding head profile provides a large bearing surface and low-profile seating, making it well suited for clamping conductors, terminal strips, and panel components. The slotted drive accepts a standard flat-blade screwdriver for installation or removal. Machined from bright, uncoated brass, this screw resists corrosion in low-voltage panel environments and does not require a washer beneath the head. Length under head measures 1/2 inch, conforming to the UNF inch measurement standard.

Binding head slotted screws in the 10-32 thread size are a common fastener in electrical enclosures, control panels, and terminal block assemblies. They are also used in HVAC control board mounting, plumbing fixture hardware, and light-duty equipment assembly where brass is specified to avoid galvanic corrosion with aluminum or copper components. Installation is performed by electricians, HVAC technicians, and general mechanical trades. This screw is sold in a minimum order quantity of 100 units per order, packaged as a single unit lot.

Key Features

• 10-32 UNF thread provides a fine-pitch, secure fit in tapped holes common to electrical and HVAC panels
• Binding head style delivers a wide, flat bearing surface for terminal and conductor clamping applications
• Slotted drive accepts standard flat-blade screwdrivers — no specialty tooling required
• Brass construction resists corrosion and is non-magnetic, suitable for sensitive electrical environments
• Bright, uncoated finish — no additional surface treatment that could affect conductivity or dimensional tolerance
• Length under head: 1/2 inch — no washer required by design

Compatibility

Designed as an OEM-style replacement or service fastener for applications requiring a 10-32 UNF binding head slotted machine screw in brass, without a washer, with a 1/2-inch length under head.

Installation Notes

Power down or de-energize any panel or enclosure before installing or removing fasteners near live conductors, per applicable NEC guidelines. Use a properly sized flat-blade screwdriver that fully seats in the slot to avoid cam-out and head damage. Do not overtighten brass fasteners into tapped steel or aluminum holes, as brass has lower shear strength than steel and threads can strip under excessive torque. Confirm thread engagement is complete before applying load.
