Made to the standard your project specifies, for example EN 14399, DIN 6914/6915/6916, ISO 7412/7414/7416, IS 3757, BS 4395 or ASTM A325/A490 (F3125). Property classes 8.8S and 10.9S, M16 to M36, lengths 40 to 500 mm. European systems from M12 to M36: HR sets to EN 14399-3 and -6, HV sets to EN 14399-4, tension-control bolts to EN 14399-10, non-preloaded sets to EN 15048, and AS 1252 sets.
Inch sets: ASTM A325 and A490 heavy hex bolts from ½ in to 1¼ in, with ASTM A563 DH or A194 2H heavy hex nuts and ASTM F436 hardened washers. Tension-control (twist-off) bolts to ASTM F1852 and F2280 are also available.
Finishes: plain (black), zinc plated, Dacromet or Geomet. Hot-dip galvanising is offered for 8.8S and A325 only: quenched and tempered 10.9S and A490 bolts are not normally hot-dip galvanised because of the risk of hydrogen embrittlement.
