Kipp K0274.2A3 Wing Knob 5/16-18 Tapped Thermoplastic

Product Description

The KIPP K0274.2A3 is a tapped bar and wing knob manufactured from thermoplastic, designed for use as a hand-tightened fastening element in light industrial, machine building, and fixture applications. The knob features a 5/16-18 internal thread with a hole depth of 0.55 inches and a head length of 2.95 inches. The hub diameter measures 1.38 inches and the hub height is 0.65 inches. Its wing-style grip allows tool-free tightening and loosening, making it well suited for panels, guards, and adjustable assemblies that require frequent manual adjustment. The part weighs 1 pound and is finished in black.

This wing knob is appropriate for use in residential and commercial equipment manufacturing, automation, and fabrication environments. It is typically installed on machine guards, fixture plates, enclosure panels, and similar assemblies where a threaded stud or bolt requires a hand-operable knob. The tapped configuration accepts a standard 5/16-18 fastener directly, eliminating the need for a separate nut. It is a common choice for maintenance technicians and equipment assemblers working with light-duty clamping and positioning hardware.

Key Features

• 5/16-18 tapped internal thread for direct fastener engagement
• 2.95 inch head length provides extended grip surface for hand tightening
• Thermoplastic construction offers corrosion resistance and light weight
• Wing knob profile allows tool-free operation in frequent-adjustment applications

Compatibility

Designed as an OEM-style replacement or direct-fit wing knob for assemblies using a 5/16-18 threaded stud or bolt requiring a hand-tightened knob element.

Installation Notes

Installation is typically performed by maintenance technicians or equipment assemblers without specialized tools. Before installation, confirm the mating stud or bolt is 5/16-18 thread form and that thread engagement depth does not exceed the 0.55 inch hole depth. Ensure the mating surface is clean and free of debris before seating the knob. Do not use impact tools or apply torque beyond hand-tight, as thermoplastic threads can be damaged by over-torquing.
