80/20 Inc. 3917 T-nut with Ball Spring 15 Series

Product Description

The 80/20 INC. 3917 is a steel T-nut with ball and spring, designed for use with 15 Series aluminum extrusion profiles. T-nuts of this type slide or drop into the T-slot channel of compatible extruded framing, providing a secure threaded anchor point for bolts, brackets, and accessories. The ball and spring mechanism holds the nut in position within the slot before final fastening, allowing for hands-free positioning during assembly. The zinc-plated steel construction resists corrosion and provides reliable thread engagement under repeated use. At 0.02 pounds, this is a lightweight fastener component suited for modular framing systems used in industrial, automation, and workstation applications.

This T-nut is intended for use with 80/20 15 Series extrusion profiles. It installs into the open T-slot channel along the profile face or end, depending on the assembly configuration. Typical applications include machine guarding, conveyor framing, workbenches, equipment enclosures, and custom fixture builds where components need to be positioned and repositioned along the extrusion without disassembling the frame. The ball and spring feature is especially useful during initial layout when multiple connection points are being set simultaneously.

Key Features

• Ball and spring retention holds T-nut in slot during assembly before final torque
• Zinc-plated steel construction for corrosion resistance and thread durability
• Compatible with profile ends or side slot entry positions
• Supports vertical positioning within the T-slot channel
• Lightweight at 0.02 pounds - suitable for high-count fastener applications

Compatibility

Designed for use with 80/20 15 Series aluminum extrusion profiles, compatible with profile end entry and side T-slot entry configurations.

Installation Notes

This component is typically installed by mechanical assemblers, millwrights, or automation technicians working with modular extrusion framing systems. Insert the T-nut into the desired slot position before or after profile assembly depending on whether end-loading or side-loading is required. Ensure the mating bolt thread specification matches the T-nut before applying final torque. Do not overtighten, as this can strip the zinc-plated threads or crack the extrusion channel wall.
