The Buyers Products 50 Ton Air Compensated Pintle Hook # 337PH50 that you referenced features 3/4 inch diameter bolt holes. Buyers Products recommends using 3/4 inch Grade 8 bolts to install the assembly.
Please just note that this particular pintle hook does not include the air chamber and plunger but the kit can be added with part # 337PH50ACMK.
