Gibraltar G10-2870-B Knurled Fluted Knob 1.625 in Plastic

Product Description

The GIBRALTAR G10-2870-B is a knurled fluted knob with a plastic body and a female threaded insert, designed for hand-adjustment applications in industrial, mechanical, and equipment assembly environments. The knob head measures 1.625 inches in diameter and accepts a 3/8-16 threaded fastener through the female insert. The knurled and fluted outer surface provides a secure grip for tool-free tightening and loosening. This type of knob is installed by technicians and assemblers wherever a finger-operated control point is needed on machinery, panels, enclosures, or fixtures.

The G10-2870-B suits applications requiring a low-profile, hand-operable fastening point. Common install scenarios include control panel assemblies, machine guards, jigs and fixtures, and enclosure covers where repeated access or adjustment is expected. The plastic construction keeps the part lightweight and resistant to corrosion, making it appropriate for both indoor industrial settings and light-duty equipment in humid or wet environments. Licensed tradespeople and industrial maintenance technicians are the typical installers.

Installation Notes

Installation requires no special tools — thread the female insert onto a 3/8-16 stud or bolt by hand until snug. Ensure the mating threaded fastener is clean and free of debris before installation. Do not use a wrench or pliers on the plastic body, as overtightening can crack the knob. Verify thread engagement depth is sufficient for the load requirements of the application before returning equipment to service.
