It features a 1-8 UNC thread size and a 7-inch length under head, making it suitable for heavy-duty clamping and bolted connections that require a wrench or pipe wrench on the head. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI\/ASME B18.2.1 dimensional standards. The square head profile provides high torque engagement in applications where a standard hex head may not be practical, such as timber framing, machinery mounting, and agricultural equipment.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in residential construction, commercial structural work, and general industrial maintenance where a 1-8 UNC coarse-thread fastener is specified. The square head allows positive wrench engagement in tight or awkward spaces and is a common choice for timber connections, framing hardware, and legacy equipment that calls out square head fasteners by specification.
