Applications and selection
Space-constrained joints specifically designed for a thin slotted nut.
Confirm overall height, thread engagement, slot depth and retaining-pin dimensions. A thin profile should not be treated as equivalent to a regular-height nut.
Dimensions & technical reference
DIN 979:2013
Thin slotted nuts have a lower body than DIN 935 nuts. Confirm available thread engagement and pin position rather than substituting by wrench size.

Catalog inquiry range: M6 - M48. Availability, lengths, grades and finishes are confirmed by quotation. Sizes outside the cited reference table require the applicable standard dimensions or an approved drawing. Quote the exact standard and edition; DIN, ISO and U.S. references are not automatically interchangeable.
Materials, surface finishes and standards
Materials for this series: Carbon Steel, Stainless Steel. Surface finishes: Zinc Plated, Nickel, Plain. Compatibility between the grade, finish and operating environment needs to be confirmed.
For titanium, nickel alloy or other non-ferrous requirements, include the exact material grade and drawing. Required mechanical properties, inspection documents and traceability should be stated in the inquiry.
A thin slotted nut may require drawing-defined height and slot geometry; do not assume equivalence with DIN 979. Standards from different systems can vary in dimensions, threads, product scope and test requirements. Confirm the exact designation and edition in the quotation.

United States references for a separate inquiry: ASME B18.2.2 (related inch reference). Confirm the exact form, thread system and drawing before quoting.
What to send for a quotation
- Hex Slotted Thin Nuts or your part number, with the relevant standard and edition.
- Exact dimensions, thread details, quantity and any critical tolerances.
- Material grade, surface finish, inspection requirements and delivery destination.
- For customization, a drawing revision and a description of the mating assembly.
Common questions about hex slotted thin nuts
Can a thin slotted nut replace a regular slotted nut?
Only when the joint design permits the different height and engagement. Compare the complete dimensions and mechanical requirements.
Can I request a size or material outside this listing?
Yes. Send the required dimensions and exact material grade for review. A quotation is needed to confirm feasibility, price and lead time.
