Gibraltar SSBK-038-G Ball Knob Threaded Hole 1 Inch

Product Description

The GIBRALTAR SSBK-038-G is a stainless steel ball knob designed for use with threaded-hole mounting applications. It features a 1.0 inch diameter spherical grip with a smooth surface finish and accepts a 5/16-24 threaded fastener with a hole depth of 0.5 inches. The natural stainless steel construction provides corrosion resistance in demanding service environments. This knob is commonly installed by HVAC technicians, electricians, plumbers, and mechanical contractors as a control or adjustment knob on panels, valves, equipment covers, and service access points.

This ball knob suits residential and light commercial applications where a compact, durable hand-actuated control is needed. It fits panels, brackets, and equipment assemblies that require a small-diameter knob with a fine-thread connection. The smooth grip profile works well in clean environments where gloved or bare-hand operation is typical. At 0.14 pounds, it adds minimal weight to any assembly.

Key Features

• Stainless steel construction for corrosion resistance in service environments
• 1.0 inch diameter spherical body provides a positive hand grip
• 5/16-24 threaded hole for secure, precise fastener engagement
• 0.5 inch hole depth accommodates standard threaded stud lengths
• Smooth grip surface suits clean-environment control applications
• Natural finish maintains the base material appearance without coating

Compatibility

Designed as a direct-fit threaded-hole ball knob for equipment panels, valve assemblies, and mechanical components that use a 5/16-24 thread pattern and accommodate a 1.0 inch diameter knob.

Installation Notes

Installation is performed by threading the knob onto a 5/16-24 stud or fastener by hand or with light tooling. Power down or de-energize the equipment before replacing any panel-mounted control knobs. Verify thread engagement depth against the 0.5 inch hole depth to avoid bottoming out the stud before the knob seats fully. Follow applicable equipment manufacturer service procedures and relevant codes for the trade discipline involved.
