The H-beam rods in our range use very high quality bolts, they are made from forged 8740 chrome molybdenum with a tensile strength of 200,000 psi. We recommend that the bolts never be used more than once, despite the very high tensile load. Reuse is acceptable in some cases, but the risk of breakage is far too high. Neither the manufacturer nor we, as importer, assume any responsibility in this regard if you reuse them.
These replacement bolts are the same as those supplied with the connecting rods. They have the strength and reliability required for H-beam rods. If you need 5/16 inch bolts for I-beam connecting rods (which we do not supply), no separate bolts are available for these, the 5/16 inch bolts we supply are for H-beam connecting rods only.
