Applications & Selection Guide
ISO 898-2 property class 5 hexagon nuts dimensioned to DIN 934 / ISO 4032, ISO metric coarse thread, standard nut height (~0.8d). Class 5 is the matching nut for ISO 898-1 class 4.8 bolts, screws, and studs — proof load is set so the nut is not weaker than the 4.8 male fastener. Metric sizes M3–M80 are listed above.
Use class 5 nuts on covers, brackets, light frames, furniture hardware, and general fabrication with 4.8 hex bolts or threaded rod. They are the wrong nut for 8.8 or 10.9 bolts: the nut threads can strip before the bolt yields. For vibration, a DIN 985 nylon-insert lock nut in class 5 is the usual upgrade; for a finished thread end use a DIN 1587 cap nut. Zinc or other coatings can be quoted.
Add metric sizes and quantities to your quote cart. Include coating and destination, and pair with matching 4.8 bolts, washers, or class 4.8 rod in the same enquiry.
