Reduced-loadability class 04. It does not automatically replace a regular class 8 nut. Jam-nut use requires a defined assembly procedure.

Table dimensions refer to the stated execution. DIN/UNI, polymer and special variants require verification of their own dimensions; they do not automatically inherit reference geometry, weight or performance.

Materials, classes, finishes and treatments

Executions are distinguished by reference, material, class and finish. DIN, ISO and UNI references do not imply dimensional equivalence or availability of every size in each material. Supply and batch documents require quotation confirmation.

Execution reference	Material	Class / hardness	Documented finishes
DIN 936	Steel	04	Black oxide; Hot-dip galvanized; Plain; Yellow zinc plated; Zinc plated; Zinc plated ≥8 µm
DIN 936	Steel	To be specified	Black zinc plated; GEOMET 321A; Hot-dip galvanized; Plain; Trivalent iridescent zinc plated; Yellow zinc plated Cr III 12 µm with sealer; Zinc plated; Zinc plated ≥12 µm

“To be specified” is a requirement not established by this selection; it does not imply class 70/80, HV hardness or an automatic finish. Steel property classes do not apply to nylon/polyamide; PA6 and PA66 are distinguished only where stated. For nuts with non-metallic inserts, the material shown is the body material.
