Knobs

Ball knobs are moulded in high strength phenolic and have a gloss finish. They are supplied with moulded or steel threads or with a tapered bore which allows the ball to be knocked onto the end of plain rod or shaft. Ball knobs with male studs can also be manufactured to order. Control knobs are primarily used on gas and electrical appliances and are moulded in both thermoset and thermoplastic materials. They are manufactured with a standard D shaft fixing which can be produced to suit various shaft sizes and orientations. Wing knobs are used primarily where maximum torque is required, wing knobs are produced in various sizes, styles and materials.Thumb knobs are available with male, female and through threads and are used for adjustment or fixing. Styles include knobs with or without boss, with solid or recessed heads, screwdriver slots and fine or heavy knurls.
