Value Collection 0305MSL Machine Screw 3-48 X 5/16 in Fillister

Product Description

The VALUE COLLECTION 0305MSL is a fillister head machine screw designed for precision fastening applications requiring a recessed, high-profile head with a slotted drive. Built from steel with a zinc finish, this screw measures 5/16 inches in length under head on a 3-48 thread and meets ASME B18.6.3 and SAE J82 dimensional and material standards. The zinc coating provides basic corrosion resistance for general-purpose use in controlled environments. This fastener is installed by electricians, HVAC technicians, plumbers, and general maintenance professionals who require a reliable small-diameter machine screw for panel assembly, equipment housings, and light-gauge component fastening.

The 0305MSL is suited for indoor mechanical and electrical assemblies where a 3-48 thread is specified. The fillister head style offers a taller head height and smaller diameter than a pan head, making it a practical choice in countersunk or confined-clearance applications. Typical uses include instrument panels, electrical enclosures, HVAC control board brackets, and similar light industrial or commercial equipment. This item is sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• 3-48 thread size with 5/16 inch length under head for precise fitment in fine-thread applications
• Fillister head profile provides a tall, narrow head suited for close-clearance installations
• Slotted drive compatible with standard flat-blade screwdrivers
• Steel construction with zinc finish for general corrosion resistance in indoor environments
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Sold without washer; length measurement type is length under head

Compatibility

Designed as a standard inch-series machine screw for any application specifying a 3-48 thread, fillister head, and slotted drive per ASME B18.6.3 and SAE J82.

Installation Notes

Install using a flat-blade screwdriver sized to the slot to avoid cam-out and head damage. Use a thread gauge or tapped hole inspection to confirm 3-48 thread engagement before driving the screw to avoid cross-threading in small-diameter tapped holes. Do not exceed the design torque for this thread size and material grade, as over-torquing steel fasteners in this diameter range can strip the thread or fracture the head. Follow applicable equipment manufacturer guidelines and relevant codes such as NFPA 70 (NEC) when securing electrical enclosure components.
