What are the DIN 434 square taper washer dimensions (size, hole, thickness) for U-section flanges, M8 to M27? · Standard part · basis: fasten.it's DIN 434 table (04/2000: d, a, b, h, e, t, r), cross-checked against Westfield Fasteners' DIN 434 table; every row satisfies e = h − 0.04 b (8 % over the half width)

Also called: din 434 dimensions, taper washer for u channel m12, 8% bevel washer m16, square bevel washer channel flange, din 434 m20 thickness

Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

sizes: 8 in table

Notes

Columns: thread, hole d, length a, width b (slope direction), thickness h at the hole axis, thickness e at the thin edge. Thick edge = 2h − e.
The 1990 edition used holes of 14 (M12) and 18 (M16); the current values are 13.5 and 17.5. The two shallow marking grooves (depth t, radius r) are not drawn.
