Description

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 1⁄2” through 11⁄4 ” diameter in most ASTM and SAE specifications. Special tooling can be created to produce nonstandard head dimensions, button head bolts larger than 11⁄4” in diameter, or bolt heads with your company’s name and/or logo.

*Dimensions per ASME B18.5 1990 (R 1998) cover diameters up to 1". Bolts over 1" use custom head dimensions.

Standard Thread Length

Bolt lengths ≤ 6″: Thread length = (2 X diameter) + 1⁄4”
Bolt lengths > 6″: Thread length = (2 X diameter) + 1⁄2”
