Mil. Spec. Piano Hinges without Holes
Choose these hinges for their adherence to strict military standards for material and construction. Longer than other hinges, piano hinges run the entire length of doors and lids for strength and durability. All of these hinges have a standard clearance—when they are closed, the distance between the leaves is about the same as the pin diameter.
302 stainless steel hinges are more corrosion resistant than aluminum. They also have good chemical resistance.
Aluminum hinges are about half the weight of steel. They have mild corrosion resistance.
Note: Prices are 15% to 20% lower when you buy 10 or more hinges of the same size.

Mil. Spec. Ball Joint Rod Ends
Made of cadmium-plated steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. They provide moderate corrosion resistance. All have a PTFE liner that allows smooth ball rotation and eliminates the need for lubrication. Liner meets SAE AS81820.
Rod ends with an oversized shank have a shank that is one size larger than the ID to handle greater stress.

Internally Threaded High-Speed Ball Bearing Rod Ends
A double row of precision ball bearings allows high speeds and smooth operation. Seals keep lubricant in and dirt out.
Cadmium-plated alloy steel rod ends offer moderate corrosion resistance. They have an oversized shank, which is one size larger than the ID, to handle greater stress. Their lubricant meets MIL-PRF-81322. These rod ends won't require ongoing lubrication.

Mil. Spec. Machinable-Bore Single U-Joints
Drill the bores to create custom U-joints that meet strict military standards for material and construction. These U-joints come apart and have a small, centered starter hole on each end to make drilling easy. Because they’re single U-joints, they connect and transfer torque between two shafts that are misaligned at an angle. They have a pin-and-block joint, so they handle higher torque at lower speeds than other joint types such as those with needle bearings, making them a good choice for most applications. Made of steel with hardened yoke ears for added strength and durability, they handle a good amount of torque.
Drill holes through the U-joint and your shafts and then connect using spring pins. They have a ball-spring oil fitting to keep lubricant in the joint.
Your shafts’ misalignment will affect the speed and torque the U-joint will be able to transmit. The more the shafts are misaligned, the less speed and torque the U-joint will be able to transmit.
