The VALUE COLLECTION 62176BMQ is a square head bolt with a 5/8-11 UNC thread size and 11 inches of length under head. Manufactured from Grade 2 steel with an uncoated finish, this fastener is built for standard-duty structural and mechanical assembly applications. The square head profile allows high torque to be applied using a wrench on two flats, making it a common choice when easy installation and reliable clamping force are both required. It conforms to ANSI/ASME B18.2.1 dimensional standards and ships individually.
Square head bolts of this size are commonly used in structural steel fabrication, timber framing, agricultural equipment, and general industrial assembly. The 5/8-11 UNC coarse thread engages standard UNC nuts and threaded inserts and is suited for use in both clean and field-service environments where thread debris or minor contamination may be present. Tradespeople and maintenance mechanics reach for this size when working with heavier structural members or equipment frames that demand a larger-diameter fastener.
Designed as a standard replacement or new-installation fastener for applications requiring a 5/8-11 UNC square head bolt with 11 inches of length under head, conforming to ANSI/ASME B18.2.1.
Installation is typically performed by a mechanic, ironworker, or maintenance technician using an appropriate box-end or adjustable wrench sized for a square head of this bolt diameter. Ensure the mating nut or tapped hole is also 5/8-11 UNC before assembly. Apply fastener torque gradually and evenly, referencing the applicable structural or equipment specification for target clamp load. Inspect threads for damage before installation and avoid cross-threading.
