Frequently Asked Questions
Is the product strictly compliant with the DIN439 standard?
Yes, the product strictly adheres to the DIN439 standard, ensuring precise dimensions and a space-saving thin design that effectively reduces installation space.
What specific type of stainless steel is used, and what is its rust resistance capability?
The standard material is typically A2-70 (304 stainless steel), offering good rust and corrosion resistance, making it suitable for most environments.
What is the exact thickness of the "thin" nut, and how does it compare to standard nuts?
Its thickness is approximately half that of a standard hex nut. While its primary function is the same as a standard nut, it can be directly substituted in space-constrained applications to reduce overall height.
What is special about the anti-loosening effect and usage as a lock nut (Jam Nut)?
It is typically used as a secondary nut paired with a primary nut, preventing loosening through jamming action, and is reusable with reliable stability.
What is the minimum order quantity (MOQ) and the regular delivery lead time?
The MOQ is usually 20 kilograms or per carton. Common specifications are available in stock with short lead times, and specifics can be negotiated based on order quantity.
