40mm diameter Cast Iron star knob DIN 6336 reamed hole

What are Cast Iron star knobs used for?

DIN 6336 knobs are robust machine handles crafted from durable Cast Iron, designed to withstand rigorous industrial use. Their sturdy construction and ergonomic star shape make them perfect for applications that demand frequent adjustments and reliable, consistent operation. These knobs are machined with a metric blind hole which means the hole does not go all the way through the knob but rather stops partway to create a hidden or blind end. This makes them idela for applications that require a secure and hidden attachment. This type of machining maintains a smooth, uninterrupted surface on one side of the knob. Blind holes are commonly used in safety equipment, control levers and machinery to prevent tampering or accidental disassembly, ensuring a clean and secure attachment.
