Value Collection 1405MSP 1/4-20 Pan Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 1405MSP is a 1/4-20 pan head machine screw with a slotted drive, manufactured from steel with a zinc finish. It measures 5/16 inches in length under the head and conforms to ASME B18.6.3 and SAE J82 standards. The zinc coating provides basic corrosion resistance for general-purpose indoor fastening applications. This fastener is suited for assembly work, equipment maintenance, and light fabrication tasks performed by electricians, HVAC technicians, plumbers, and general maintenance professionals working with threaded metal components.

This screw is commonly used in panel assembly, junction box mounting, equipment enclosures, and general mechanical assembly where a 1/4-20 unified coarse thread is specified. The pan head profile sits low and distributes clamping load across a wider bearing surface compared to a round head, making it a practical choice for sheet metal and thin-stock applications. It is sold in multiples of 100 units per order with a package quantity of 1.

Key Features

• 1/4-20 unified coarse thread for broad tooling and hardware compatibility
• Pan head profile provides wide bearing surface for sheet metal and panel work
• Slotted drive compatible with standard flat-blade screwdrivers
• Zinc finish offers basic corrosion resistance for indoor and dry environments
• Meets ASME B18.6.3 and SAE J82 dimensional standards
• Steel construction for reliable tensile and shear strength in general-purpose fastening

Compatibility

Designed as a general-purpose 1/4-20 machine screw for use wherever ASME B18.6.3 pan head slotted fasteners are specified in mechanical assemblies, enclosures, and equipment panels.

Installation Notes

Install using a standard flat-blade screwdriver sized to fit the slotted head. Ensure the mating component has a properly tapped 1/4-20 thread or an appropriate nut and clearance hole. De-energize any electrical equipment before fastening into or near live enclosures, in accordance with applicable NEC requirements. Do not over-torque; steel screws at this thread size are susceptible to thread stripping in soft base materials.
