What is a Hi-Lok collar?

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.

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 is a Hi-Lok bolt?

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.

How are hi-Lok Fasteners measured?

Hi-Lok® Grip Gauge with Slide. Slide the tip of this gauge through a hole, draw the gauge back until the hook hits the backside of the hole and you’ll be able to correctly determine the proper length of the Hi-Lok® fastener needed.

What are the advantages of hi Lok fasteners?

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.

Who makes Hiloks?

What is a high lock?

High security locks are designed to provide a greater level of protection against the primary methods of attack that are employed by criminals, saboteurs, and spies – both outside of a protected area and from within by employees, service personnel, or those who may have or gain access to one or more locks.

What are Hihi-Lok collars?

Hi-lok collars are used in conjunction with hi-lok head pins to form a secure joint through the use of a the 2 threaded pieces. Designed for specific applications the new threaded hi-lok systems are easier to install and maintain with less special tooling needed.

What is Hi Lok used for?

Hi-Lok Fasteners. Hi-Lok is a registered trademark of the Hi-Shear Corporation. Hi-Lok pins are commonly used in applications that require high tensile strength in extreme environments. Hi-Loks pins and Hi-Lok collars offer extremely precise dimensions making Hi-Lok fasteners commonly used in space, military, and commercial aviation application.

What are Hihi-Lok pins?

Hi-Lok is a registered trademark of the Hi-Shear Corporation. Hi-Lok pins are commonly used in applications that require high tensile strength in extreme environments.

What are Hi-Lite™ pins?

HI-LITE™ pin (HST) 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.
