Value Collection 0404MSB 4-40 X 0.25 in Binding Head Screw

Product Description

The VALUE COLLECTION 0404MSB is a 4-40 x 0.25 inch binding head machine screw designed for general fastening applications in mechanical assemblies. It features a slotted drive and zinc-plated steel construction, conforming to ASME B18.6.3 and SAE J82 standards. The binding head profile provides a wide, low-profile bearing surface that resists pull-through and is commonly used where wiring or thin material must be clamped securely. Length is measured under the head. This fastener is handled routinely by electricians, HVAC technicians, and mechanical assemblers working on control panels, enclosures, and equipment housings.

This screw is suited for light-duty fastening in residential and commercial settings. Common applications include securing terminal blocks, control boards, and panel components in electrical enclosures and HVAC equipment. The 4-40 thread size is a standard unified coarse pitch frequently found in instrument panels and small appliance assemblies. Sold in a minimum order quantity of 100 pieces per order.

Key Features

• Binding head profile provides wide bearing surface, ideal for clamping wiring and thin stock
• Slotted drive compatible with standard flat-blade screwdrivers
• Zinc-plated finish for basic corrosion resistance in indoor environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Steel construction, Material Grade J82, for reliable tensile performance in light fastening applications
• Inch measurement system; length measured under head at 0.25 inches

Compatibility

Designed as an OEM-style replacement or general-use fastener for assemblies specifying a 4-40 binding head slotted machine screw per ASME B18.6.3.

Installation Notes

Installation is performed with a standard flat-blade screwdriver sized to the slotted head. Always verify that the mating tapped hole or nut conforms to 4-40 thread specifications before installation. Avoid overtightening, which can strip the 4-40 thread in soft materials. Follow applicable NEC or equipment manufacturer guidelines when installing fasteners inside electrical enclosures.
