About U-Joints (Universal Joints)

U-joints are used to connect two shafts that have a high amount of misalignment.

Single U-Joints

These U-joints are made of steel or zinc.

Corrosion-Resistant Single U-Joints

Made of stainless steel, these U-joints offer excellent corrosion resistance.

Corrosion-Resistant Mil. Spec.
Machinable-Bore Single U-Joints

Made of stainless steel, these U-joints offer excellent corrosion resistance. They also meet MIL-U-20625A Class A.

Mil. Spec. Machinable-Bore
Single U-Joints

These steel U-joints meet MIL-U-20625A Class A and have hardened yoke ears for added strength and durability.

Machinable-Bore Single U-Joints

These U-joints are made of steel.

Easy-Install Single U-Joints

These U-joints are made of steel or plastic.

Corrosion-Resistant
Precision Single U-Joints

Stainless steel U-joints are more corrosion resistant than steel U-joints.

Precision Single U-Joints

These joints are made of steel.

Corrosion-Resistant Sealed
Easy-Install Single U-Joints

Stainless steel hubs allow these U-joints to handle harsh environments.

Sealed Easy-Install Single U-Joints

These joints are made of steel.

High-Torque Easy-Install
Single U-Joints

These U-joints handle at least 11,000 in.-lbs. of torque.

Corrosion-Resistant
High-Speed Single U-Joints

Made of stainless steel, these U-joints offer excellent corrosion resistance.

High-Speed Single U-Joints

These joints are made of steel.

Extreme-Angle Geared
Single U-Joints

A set of gears transmit rotary motion at angles up to 136°—the widest angle of all our U-joints. They are for hand-powered, low-speed applications.

Constant-Velocity Single U-Joints

Keep shafts moving in sync with these U-joints—a flexible spring at the center stabilizes input and output speed and reduces vibration.

Double U-Joints

Precision Double U-Joints

Joints have a fixed 2 1/2" overall length.

Adjustable-Length
Precision Double U-Joints

Adjust the length of these U-joints between 2 3/4" to 3" to fit your application.

Machinable-Bore Double U-Joints

Customize the bore size of these joints to fit your shaft. Each end has a small centered starter hole that makes drilling easy.

Double U-Joints

These pin-and-block style U-joints work at lower speeds but transmit greater torque than needle-bearing joints.

Building and Machinery Hardware

Plastic Piano Hinges without Holes

Plastic hinges are a lightweight alternative to metal hinges and provide smooth, silent operation.

Slip-On Piano Hinges

No need for drilling holes or welding, slip these hinges onto panel and door edges for a secure fit.

Plastic Hinges with Holes

Plastic hinges are a lightweight alternative to metal hinges and provide smooth, silent operation.

U-Joint Covers

Protect U-joints to keep lubricants in and contaminants out.

Socket Adapters and Extensions

Flex Socket Adapters

Pivot the head to access fasteners from an angle.

Impact Flex Socket Adapters

Pivot the head to access fasteners from an angle.
