2.U-BOLT USE
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.
U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such,
U-bolts were measured using pipe-work engineering speak.
U bolts available in a range of sizes and finishes to support different loads, torque requirements and environments. U Bolts usually available from stock.
A U-bolt is an industrial fastener in the shape of the letter U with two threaded arms (or legs) extending from a curved base. U bolts are typically used to support pipework or to attach a part to a pole, beam or wall, where the “u” shape keeps it firmly in place, adding stability to the support.
The threaded ends are designed for use with washers and screws, and can also be used with a crosspiece spanning both threaded arms of the bolt, to make it more secure in certain settings and uses. U-bolts are designed to be inserted through holes that have already been drilled or punched.
U-bolt specifications include:
1.Material Type (For example: zinc plated mild steel)
2.Thread dimensions (For example: M12 * 50 mm)
3.Inside diameter (For example: 50 mm – the distance between the legs)
4.Inside height (For example: 120 mm) Suitable for automotive, plumbing, construction and other home and industrial applications.
U bolts are often used as framing fasteners and anchors for foundations and roofs, pipe and conduit holders and bolts for motor and engine shaft components.
