DIN 435 - Square taper washers for I-sections

Automatically build standard products in SOLIDWORKS with TSFP.

Paid access

Square taper washers with one face sloped by 14 % for the flanges of I-sections (I-beams), unlike the flat DIN 436 and steeper than the 8 % of DIN 434 for U-sections. They square the seat of a bolt or nut on the sloped inner flange of an I-beam, in structural bolting up to property class 5.6. The washer is a by b with a central hole d; one face slopes across b by 14 %, the other is square to the bolt and carries one groove that marks the slope. The thickness h is measured at the hole axis. Covers bolts M8 to M27. The current 2024 edition replaces DIN 435:2000-01 with editorial changes only, so the dimensions are those of the 2000 edition.
