We provide hexagon head bolts and sets in BS1769, BS1768, BS1083, DIN926, DIN 931, DIN 933, ANSI / ASME B18.2.1 table 2, 3, 4 and 6, ISO 4014 and ISO 4017.
Studbolts, studs and studding
We supply studbolts in cut lengths and studding in full bar lengths up to 4m long, according to Din 975, Din 976, BS4882, BS4439, Din 938, and ANSI / ASME B16.5.
Socket capscrews, countersunk screws and setscrews
We offer socket capscrews, socket countersunk screws and socket setscrews in BS4168, BS2470, Din 912, ANSI / ASME B18.3 and ISO 4762.
Washers, bolts and studs
We manufacture a range of other products, including washers, cup square bolts, fitted bolts, U bolts, slotted countersunk screws, manway studs, bobbins, connectors, flange head and 12-point head bolts, square bolts and J-bolts.
Non-standard special fasteners
To compliment our hot forging facilities, we have a wide variety of conventional lathes, automatic lathes, CNC lathes, hydraulic presses, drilling machines and milling machines. This enables us to produce fasteners outside the standard range and length stated above. For example, M3 x 30mm long socket capscrews in Hastelloy C276®, or 1in unc x 36in long studbolts in aluminium bronze.
