What is a Star Grip Knob?

This star grip knob is designed for ergonomic control and reliable clamping in demanding environments. It features a seven-lobed shape for improved grip and torque distribution. The knob is constructed from durable black thermoplastic with a precision-machined 303 stainless steel bush for strength and corrosion resistance. A removable black cap allows for use as a closed design or a counterbored version, offering flexibility for different mounting configurations.

What is DIN 6336?

DIN 6336 is a German industrial standard specifying the design, dimensions, and material requirements for star knobs used in mechanical and industrial settings. It ensures consistency and interchangeability across manufacturers. Star knobs following this standard are widely used in clamping and positioning applications, offering a safe and secure grip for manual adjustments.

Design Features

This knob features a seven-lobed ergonomic design, providing enhanced grip and torque transfer compared to traditional round knobs. The body is moulded from impact-resistant black thermoplastic, offering durability and resistance to oils and chemicals. The insert is made from 303 stainless steel for excellent corrosion resistance, making it suitable for use in aggressive or hygienic environments. The central cap is removable, giving users the choice between a sealed design or access to a counterbored centre hole.

Benefits of a Stainless Steel Bush

The 303 stainless steel bush provides a strong, wear-resistant internal thread for repeated tightening and loosening. It also protects against thread stripping in frequent-use scenarios. Stainless steel offers excellent corrosion resistance, making it ideal for food processing, marine, pharmaceutical, and outdoor equipment. Its high strength and resistance to galling make it well-suited to mechanical fastening applications.

Typical Applications

These star grip knobs are commonly used on machine guards, jigs and fixtures, tooling plates, laboratory equipment, and adjustable furniture. Their hygienic and chemical-resistant construction makes them suitable for cleanroom and washdown areas. The removable cap adds flexibility, allowing both blind and through-hole mounting, making them an excellent all-round choice for both OEM and maintenance applications.

Versatility with Removable Cap

The knob’s removable black cap transforms its functionality. In standard form, the cap keeps the top sealed for a sleek, hygienic finish. When removed, It reveals a counterbored section, making it compatible with bolt-through assemblies or applications requiring access to the fixing from above. This dual-mode capability provides enhanced design freedom and simplifies inventory management.
