Hi-Lok Pins The Hi-Lok fastening system is comprised of a threaded pin and a collar that is specially designed with a break-off groove that separates at a uniform preload value. This means that the part provides consistent and optimal torque.
What is HI-Lok rivet?
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 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.
What is a huck bolt?
Huck® Lockbolts are precision engineered two-piece fasteners that, once installed, no matter how vibration-intensive the environment, never come loose. The pin and swaged collar combine to form the installed fastener. The squeezing action reduces the diameter of the collar, increasing its length.
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 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?
Why are blind fasteners used in aircrafts?
Hex, close-tolerance, and internal wrenching bolts are used in aircraft structural applications. Blind bolts have a higher strength than blind rivets and are used for joints that require high strength. Blind bolts are difficult to remove due to the hardness of the core bolt.
How do you remove a Huck rivet?
Use a grinder and go slow. Once the rivet gets thin then u can punch it out. Amazing how strong those huck rivets are.
What is a huck bolt used for?
Today, Huck bolts are made out of a variety of materials, with many different styles for specific applications. Huck fasteners are most often used in manufacturing, mining equipment, shipbuilding, and agriculture, as well as in trucks, trailers, bridges, railways, and railcars, where vibration is ever-present.
What is a Composi Lok?
An industry standard for blind fastening of composite joints Designed for use in composite laminates but equally well suited to metal structure, the Composi-Lok® family of fasteners provides superior joint integrity.
What is Hi-Lok fastening?
The Hi-Lok fastening system is comprised of a threaded pin and a collar that is specially designed with a break-off groove that separates at a uniform preload value. This means that the part provides consistent and optimal torque.
What are Hi-Lok™ pins?
The HI-LOK™ pins are the original solution for strong and reliable assemblies. Having a wide range of shapes, materials and coatings, they are suited for most of structural assemblies. This solution is still commonly used in the aerospace industry, but can be safely replaced by equivalent HI-LITE™ pins for improved weight saving.
How does the Hi-Lok® collar work?
The Hi-Lok® pin is held stationary by the installation tool while the collar rotates. Progressive tightening takes place as torque is applied. At the designed torque level built into the Hi-Lok® collar, the hex portion of the collar is sheared off automatically by the driving tool.
What are hilok pins used for?
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.
