Fit-up bolts and erection bolts for structural steel

Fit-up bolts (also called fitting-up, erection or service bolts) hold beams, girders, splices and bracing in place while steel is aligned and plumbed, before the permanent bolts are tensioned. Retmay Distributors special orders fit-up bolts for steel erectors, fabricators and bridge contractors in Pennsylvania, Maryland, New Jersey and Delaware. They aren't listed in the online catalog, so send us what your drawings call for and we'll quote by email.

What we can quote

• A307 bolts for temporary erection and snug-tight connections.
• ASTM F3125 Grade A325 heavy hex structural bolts, when your project spec calls for high-strength fit-up bolts or for using the permanent bolts during fit-up.
• Matching heavy hex nuts and hardened washers, packed as sets.
• Plain or galvanized finish, by the box or in bulk job quantities.

What to send with your request

• Diameter and length (or grip), and thread pitch if not standard UNC.
• Grade and finish, or the spec section that applies.
• Nuts and washers needed, and quantity of each.
• Job name, ship-to location and the date you need them on site.

Before you order

Most specifications require fit-up bolts with the same nominal diameter as the permanent connection bolts. Some also limit reuse: for example, galvanized or A490 bolts that served as fit-up bolts may not be allowed in the final connection. Check your project specification and erection drawings, and tell us which section applies so we quote the right parts.
