    GR2 Bolt Round Head Square Neck

    304 GR2 HDG YZP BALCK ZP SAE J429 Bolt Round Head Square Neck


    Specification


    Round head bolts (button head) are commonly used in wood connections. Round head bolts are similar to carriage bolts, but without the square neck under the head. Because they are used with wood, round head bolts are rarely high strength and virtually always supplied in a standard ASTM A307 specification

    Manufacturing

    QBH Bolt manufactures button head bolts from 12” through 114 ” diameter in most ASTM and SAE specifications. Special tooling can be created to produce nonstandard head dimensions, button head bolts larger than 114” in diameter, or bolt heads with your company’s name and/or logo.
