40mm diameter Cast Iron knob reamed hole

What are Cast Iron star knobs used for?

These Cast Iron DIN 6335 Knobs are high-quality, ergonomically designed machine handles commonly used in various industrial applications. These robust and versatile knobs are crafted to ensure a secure and comfortable grip, making them ideal for adjustments and operations on machinery and equipment. This version is machined with a metric blind hole, which involves creating a hole that does not go all the way through the knob. Instead, the hole stops partway into the material, creating a hidden or "blind" end. The benefit of blind hole knobs are typically used in applications where a secure and hidden attachment is needed. This type of machining is advantageous for maintaining a smooth and uninterrupted surface on one side of the knob. Blind Holes are commonly used in safety equipment, control levers, and machinery where it is important to prevent exposure to the internal fastening mechanism, reducing the risk of tampering or accidental disassembly.
