Value Collection 0308MSL 3-48 X 0.5 in Fillister Slotted Screw

Product Description

The VALUE COLLECTION 0308MSL is a 3-48 unified fine thread machine screw with a fillister head and slotted drive, manufactured from steel with a zinc finish. This fastener measures 0.5 inches in length under the head and meets the requirements of ASME B18.6.3 and SAE J82. The fillister head profile offers a taller head height and smaller diameter than a pan head, making it well suited for counterbored holes and close-clearance assemblies. Electricians, instrumentation technicians, and mechanical assemblers install this screw in light-duty panel, chassis, and component applications where a compact, recessed head is preferred.

This screw is used in residential and commercial settings wherever 3-48 thread engagement is required. Typical applications include securing electrical panel components, instrumentation housings, small motor covers, and general light-gauge metal or plastic assemblies. The slotted drive accommodates standard flat-blade screwdrivers, making it accessible in confined spaces where hex or Phillips tooling may not fit. The zinc finish provides basic corrosion resistance suitable for indoor and sheltered environments.

Key Features

• 3-48 unified fine thread for reliable engagement in light-duty assemblies
• Fillister head profile designed for counterbored holes and close-clearance applications
• Slotted drive accepts standard flat-blade screwdrivers
• Steel construction meets material grade J82 per SAE J82 and ASME B18.6.3
• Zinc finish provides basic indoor corrosion resistance
• No washer, offering a clean seating surface against the mating material

Compatibility

Designed as an OEM-style replacement or general-use fastener for applications requiring a 3-48 unified fine thread, fillister head, slotted machine screw meeting ASME B18.6.3 and SAE J82 standards.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slotted recess without slipping, which can damage the head or surrounding material. Confirm the mating thread is tapped to 3-48 specification before driving the screw. Do not overtorque; the small diameter makes this fastener susceptible to thread stripping in soft materials. This fastener is intended for indoor or sheltered use only given its zinc finish.
