U-shaped Screw

Name: U-shaped Screw
Brand: Shenzhen Xintegu Hardware Co.,Ltd.

The U-shaped Screw, also known as a U-bolt, is a highly versatile and robust fastener designed to securely anchor pipes, conduits, and cables to surfaces. This screw features a U-shaped curve with threaded arms that allow it to be easily attached around the item being secured, providing a firm grip that prevents movement. Made from durable materials, the U-shaped Screw is built to withstand both mechanical stress and environmental elements, making it suitable for a wide range of applications including plumbing, electrical installations, and automotive systems. Its straightforward design ensures easy installation and adjustment.

Load Ratings and Strength of U-shaped Screw

Material and Construction: U-bolts are commonly made from steel or stainless steel. Steel U-bolts offer high strength for heavy-duty applications, while stainless steel U-bolts provide excellent corrosion resistance but may have slightly lower tensile strength.

Diameter and Thread Size: The load rating of a U-bolt increases with its diameter and thread size. Larger diameters and appropriate thread sizes can handle greater forces, but the overall strength also depends on the material used.

Load Ratings: Manufacturers provide specific load ratings for U-bolts, which can range from a few thousand pounds to over 10,000 pounds. It's essential to consult these ratings and consider safety factors to ensure the U-bolt is suitable for the intended application.

U-Bolt vs. J-Bolt: Which Fastener Is Right for Your Project?

Understanding the Differences

U-bolts and J-bolts are both curved fasteners, but their designs and applications vary significantly:

Feature	U-Bolt	J-Bolt
Shape	U-shaped with two threaded arms	J-shaped with one threaded end
Primary Use	Clamping pipes, cables, or round objects	Anchoring structures to concrete or masonry
Load Direction	Radial (holds objects in place)	Axial (vertical tension resistance)
Installation	Requires nuts on both ends	Embedded into concrete during pouring

When to Choose a U-Bolt

Industrial Piping: Secure HVAC ducts, hydraulic lines, or exhaust systems.
Automotive: Mount leaf springs, shock absorbers, or fuel tanks.
Marine: Fasten rigging wires or deck fixtures (use 316 stainless steel for saltwater).

Example: A solar farm used galvanized U-bolts to anchor panel rails to steel beams, resisting wind loads up to 130 mph.

When to Choose a J-Bolt

Construction: Anchor steel columns to concrete foundations.
Telecom: Stabilize utility poles or antenna towers.
Safety Rails: Bolt handrails to floors in commercial buildings.

Example: A warehouse used hot-dip galvanized J-bolts to secure storage racks to concrete, supporting 10,000+ lb loads.

Decision Checklist

Load Type: Radial (U-bolt) vs. Vertical (J-bolt).
Environment: Stainless steel for corrosion; carbon steel for indoor use.
Installation Time: U-bolts are faster to retrofit; J-bolts require pre-embedding.
