What is a Hi-Lok fastener?

What is a Hi-Lok fastener?

The Hi-Lok™ fastener is a simple two-part fastener that suits many of today’s aerospace assembly needs. The all-purpose fastener can create a consistent torque on each fastener installed through integrated functions.

What is the difference between hi-Lok and hi lite?

HI-LITE™ pins are the direct evolution of HI-LOK™ pins. These fasteners can be used for clearance, or low interference fit throughout aircraft, from wings to fuselage, in engine fairings, and more. Combined with HI-LITE™ nuts and collars, they provide up to 13% weight saving compared to the previous HI-LOK™ generation.

What are hi loks made of?

The advantages of Hi-Lok® two-piece fastener include its light weight, high fatigue resistance, high strength, and its inability to be overtorqued. The pins, made from alloy steel, corrosion resistant steel, or titanium alloy, come in many standard and oversized shank diameters.

What is a Hi-Lok pin?

The Hi-Lok fastening system consists of two parts, a threaded pin and a threaded collar. It combines the best features of a rivet and a bolt-nut system. We stock a wide range of both the pins and collars under the HL part numbers as well as under OEM drawings like Bombardier and Boeing. HL10. HL11.

How are hi Lok Fasteners measured?

The thicker side of the Grip Scales measure the grip-length of Hi-Lok® and Hi-Lite® pins, Shear Lockbolts, structural screws, and bolts. The thinner side measures the thickness of materials to be fastened.

What is an Eddie bolt?

The Eddie-Bolt® 2 is a high-performance aerospace fastening system. The Eddie-PinTM is designed with five flutes in the upper portion of the threaded area which allow a positive mechanical lock to be made during installation with the free-running Eddie-NutTM.

What is a jo bolt?

Jo-bolt. A patented, high-strength structural fastener used where strength requirements are high. The Jo-bolt is passed through a close-tolerance hole, and a sleeve is pulled up over its tapered shank to form a blind head inside the structure.

What is a locking bolt?

Definition of lock bolt 1 : bolt sense 2b. 2a : a bolt or pin employing a special locking collar instead of a nut. b : a bolt for securing an adjustable part of a machine in a desired position.

Who makes Hiloks?

the Hi-Shear Corporation
HI-LOK is a registered trademark of the Hi-Shear Corporation.

How Lockbolt are installed?

Lockbolt installation is relatively simple. A pin is placed through the pre-drilled holes to join two pieces of material. The pin has a head chosen to suit the application, such as a rounded head, countersunk head, or extra wide head for softer material to prevent pull-through.

How do Eddie bolts work?

The Eddie-Bolt® 2 pin is designed with five flutes in the upper portion of the threaded area. Torque is applied, and upon reaching the required clamp load, the lobes automatically deform into the flutes of the Eddie-Bolt® 2 pin.
