Value Collection 0412MSB 4-40 Binding Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0412MSB is a 4-40 binding head machine screw designed for precision fastening in light mechanical assemblies and electronics. The binding head profile sits low and wide, providing a larger bearing surface than a standard pan head, which helps distribute clamping load and reduce material distortion. The slotted drive accepts a standard flat-blade screwdriver for installation and removal. Manufactured from steel with a zinc finish, the screw measures 0.75 inches in length under head and meets the ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade.

This screw is suited for applications in electrical enclosures, control panels, instrumentation, and light-duty mechanical assemblies where a 4-40 thread is specified. The zinc finish provides a basic level of corrosion resistance for indoor and sheltered environments. This fastener is installed by electricians, electronics technicians, and mechanical assemblers working with standard inch-series hardware. The minimum order quantity is 100 pieces per order.

Key Features

• 4-40 UNC thread for use with standard inch-series tapped holes and nuts
• Binding head profile offers a wider bearing surface than pan or round head styles
• Slotted drive compatible with standard flat-blade screwdrivers
• Steel construction with zinc finish for basic corrosion resistance in indoor environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• 0.75-inch length measured under head for consistent fitment in threaded assemblies

Compatibility

Designed as a standard inch-series 4-40 machine screw for use in any application requiring a binding head, slotted drive fastener with 0.75-inch length under head in a 4-40 tapped hole or with a matching 4-40 nut.

Installation Notes

Power down or de-energize any electrical assembly before installing or removing fasteners in live enclosures or control panels. Use a properly sized flat-blade screwdriver that fully seats in the slot to avoid cam-out and head damage. Do not over-torque small machine screws into tapped plastic or thin sheet metal, as stripping is common at this thread size. Follow applicable assembly or equipment manufacturer specifications for torque requirements.
