ISO 4035 Hex Thin Nuts (Chamfered)
ISO 4035 hex thin nuts, chamfered — the reduced-height metric hex nut, M1.6 to M64 — with the full collected 29-size table: pitch, countersink and bearing-face diameters, nut height, effective bearing height, and across-flats tolerances.

Specifications
ISO 4035 is the thin chamfered hex nut: the same across-flats series as ISO 4032 in a height of roughly half the thread diameter. The reduced height buys clearance — on stud ends where full-height nuts would bottom out, on adjustments where a jam nut is backed against a working nut, and on long threaded rods where multiple nuts stack. The cost is engagement: the m w effective bearing height row in the table shows how little thread the thin form develops, which is why thin nuts are not the clamping nut in a strength-critical joint — they either lock against a full-height partner or work on short, low-load engagements. The collected table runs M1.6 to M64, the widest ladder of this batch. For the unchamfered jam-nut form and its inch-side pairing see the DIN 439 jam nut page; the DIN 985 nyloc page covers the insert-lock thin-height form. Property class and finish follow the drawing callout and are not part of the collected table.
| Standard | ISO 4035 — hexagon thin nuts (chamfered) |

Frequently asked questions
When is a thin nut the right choice, and when must it not be the only nut?
Right choice: thread run-up on studs, jam-nut locking against a full-height nut, clearance-constrained assemblies, and position adjustment on threaded rods. Wrong choice: any joint where the thin nut alone carries the clamping load — its effective bearing height (m w in the table) develops only a fraction of the bolt's tensile strength before its threads strip. If the application needs locking without a partner nut, use a prevailing-torque form such as DIN 985 or DIN 980 instead of thinning down a plain nut.
What is the MOQ and lead time for this nut type?
The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days; non-stock items are confirmed at quotation. Common diameters in this nut type are widely stocked; confirm the exact schedule against quantity and size mix at quotation.
