Value Collection 587681PR 1/4-20 X 3-1/2 Pan Head Phillips Screw

Product Description

The VALUE COLLECTION 587681PR is a 1/4-20 pan head machine screw designed for general-purpose fastening in metal assemblies, equipment enclosures, brackets, and mechanical fixtures. The screw measures 3-1/2 inches in length under head with a Phillips drive profile, allowing installation with standard Phillips bits or driver tips. Constructed from steel with a zinc finish for basic corrosion resistance, this fastener meets ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and mechanical performance expectations. It is a common screw size suited for maintenance, fabrication, and assembly work across a range of trade and industrial applications.

This screw is appropriate for use in light to medium fastening applications where a 1/4-20 thread form is specified. The pan head profile provides a wide bearing surface and low-profile head suited to flush or surface-mount installations. Electricians, HVAC technicians, plumbers, and general contractors frequently use 1/4-20 machine screws when assembling equipment panels, mounting components, or securing sheet metal and structural brackets. The Phillips drive is compatible with commonly available hand and power tools across trade settings.

Key Features

• 1/4-20 unified coarse thread for broad hardware compatibility
• 3-1/2 inch length under head for deeper fastening applications
• Pan head profile provides wide clamping surface with low-profile head
• Phillips drive accepts standard bits and screwdrivers
• Steel construction with zinc finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards

Compatibility

Designed as a standard 1/4-20 machine screw replacement or new-installation fastener suitable for use in any application specifying a 1/4-20 x 3-1/2 inch pan head Phillips drive screw per ASME B18.6.3.

Installation Notes

Install using a Phillips screwdriver or a No. 2 Phillips bit with a hand drill or impact driver set to low torque. Always pre-drill or use a tapped hole matching the 1/4-20 thread specification before driving. Avoid over-torquing, which can strip threads in softer base materials. Follow applicable codes and equipment manufacturer specifications when using fasteners in structural or electrical enclosure applications.
