Product information
High-strength structural bolt sets are used where a steel connection must carry load without slipping. The set is supplied as a matched bolt, nut and hardened washer so the assembly is tightened as one system rather than from mixed stock.
Typical use is beam-to-column connections, bracing joints and splice plates. Confirm bolt grade, diameter, thread length and grip length from the connection drawing; sets can be packed per connection detail to simplify site issue.
