Product Description
3/4" UNC Grade 8 Yellow Zinc Plated Part Threaded Hex Head Bolts
3/4" UNC hexagon head bolts manufactured from Grade 8 high tensile steel with a yellow zinc plated finish. These bolts feature a partially threaded shank and a 3/4"-10 UNC coarse thread for use with matching nuts or tapped holes.
The hexagon head allows installation using a spanner or socket, while the plain section beneath the head provides an unthreaded bearing surface within the assembled joint.
