Te-co 43612 Ball Knob 1-7/8 in Plastic Black 1/2-13

Product Description

The TE-CO 43612 is a plastic ball knob designed for manual clamping, adjustment, and positioning applications in industrial and trade settings. The knob measures 1-7/8 inches in diameter and features a 1/2-13 threaded hole with a depth of 5/8 inches. Its spherical grip geometry allows operators to apply turning force from multiple angles, which is useful in tight or awkward setups. The black plastic construction keeps weight low at 0.2 pounds and resists corrosion in typical shop and field environments. Machinists, maintenance technicians, and fixture builders are the primary installers of this hardware.

This ball knob is suited for use on machine tools, jigs, fixtures, and clamping assemblies where a positive manual grip is needed. The 1/2-13 thread is a common unified coarse thread size, making this knob compatible with a wide range of standard threaded studs, bolts, and clamping screws found in both light manufacturing and maintenance-repair-operations environments. It is typically used on workholding fixtures, tool rests, and adjustable guards in shop settings.

Key Features

• 1-7/8 inch diameter ball grip allows multi-angle hand torque application
• 1/2-13 UNC threaded hole for compatibility with standard coarse-thread fasteners
• 5/8 inch hole depth provides adequate thread engagement for secure mounting
• Plastic construction reduces weight and resists corrosion
• Black color finish for clean, consistent appearance on equipment and fixtures

Compatibility

Designed as a direct-fit manual control knob for applications using 1/2-13 unified coarse threaded studs or bolts in industrial fixtures, clamping systems, and machine tool assemblies.

Installation Notes

Installation requires no special tools beyond the threaded stud or bolt the knob will mount to. Ensure the mating thread is clean and free of burrs before threading on the knob. Hand-tighten only to avoid cracking the plastic body. Always de-energize or lock out any equipment before adjusting or replacing manual control hardware per applicable safety procedures.
