Value Collection 3132MSL 5/16-18x2 Fillister Slotted Machine Screw

Product Description

The VALUE COLLECTION 3132MSL is a fillister head machine screw designed for general-purpose fastening applications in metal assemblies and mechanical components. It features a 5/16-18 unified coarse thread and a 2-inch length under head, giving installers a reliable grip depth in standard tapped holes. The slotted drive allows installation with a flat-blade screwdriver or bit. Constructed from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 standards, making it a compliant choice for applications that require a documented fastener grade.

This machine screw is suited for use in light industrial, mechanical, and assembly applications where a fillister head profile is required. The fillister head provides a smaller outer diameter and taller head height compared to a pan head, allowing it to seat inside counterbored holes or confined spaces. It is commonly installed by machinists, millwrights, maintenance technicians, and general trade professionals working with threaded metal components. No washer is included or required for standard installations of this fastener.

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 5/16-18 threaded fastener with a fillister head and slotted drive, including tapped metal assemblies and pre-drilled mechanical components.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician using the appropriate flat-blade screwdriver or bit sized for the slotted drive. Confirm the mating thread is 5/16-18 before installation to avoid cross-threading or stripping. Do not exceed the torque capacity of the fastener grade; consult ASME or SAE published torque tables for Grade J82 steel fasteners if specific torque values are required. Inspect the receiving material for thread condition before fastening.
