Choosing hex bolts and nuts
Match the thread first: metric, UNC, UNF or BSW. Then match the strength class or grade to the job. Class 8.8 and imperial Grade 8 are high tensile for heavier loads, and Class 4.6 and Grade 2 suit lighter general fastening. Choose the finish to suit where the bolt will live: plain for indoor and dry use, zinc plated for general use and hot dip galvanised for outdoor work.
Use a nut and washer that match the bolt grade. Always check the data sheet. Confirm the size, class and finish before you order, especially for structural or lifting work.
