What is the difference between hi-Lok and hi lite?
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.
Who makes Hiloks?
the Hi-Shear Corporation
HI-LOK is a registered trademark of the Hi-Shear Corporation.
What is a Hi Tigue fastener?
The HI-TIGUE™ fastener design features a subtle bead on the end of the shank. This dramatically increases the total fatigue life and overall performance of the fastened structure through controlled interference fit.
What is one advantage of hi Lok fasteners over earlier generations?

| The markings on the head of a Dzus fastener identify the… | Body diameter, type of head, and length of the fastener |
What is a Hi Lite?
Informal spelling of highlight. The hilite of the show. Informal spelling of highlight. The Board also wish to hilite that the copy of the Sales & Purchase Agreeement is available for inspection. You can hilite the text with your mouse, then right-click to copy it.
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.
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.
Which special Rivet Fastener was developed for attaching rubber deicing boots to aircraft wings?
Also known as blind threaded inserts, rivet nuts provide strong fastening threads in thin panels. The fasteners were originally developed decades ago by B.F. Goodrich to attach rubber de-icing boots to airplane wings.
What is HI shear rivets?
A pin fastening system, or high-shear pin rivet, is a two-piece fastener that consists of a threaded pin and a collar. The metal collar is swaged onto the grooved end, effecting a firm tight fit. They are essentially threadless bolts.
What is the minimum edge distance for aircraft rivets?
The minimum edge distance for universal rivets is 2 times the diameter of the rivet; the minimum edge distance for countersunk rivets is 2 1⁄2 times the diameter of the rivet. If rivets are placed too close to the edge of the sheet, the sheet may crack or pull away from the rivets.
What do the markings on top of Dzus fasteners indicate?
C- three times the thickness of the thickest sheet. C- they can be installed with ordinary hand tools. 7- The markings on the head of a Dzus fastener identify the. A- body diameter, type of head, and length of the fastener.
What are the features of Hi Lok fasteners?
HI-LOK is a simple two-part fastener engineered to achieve in one all-purpose system the design features suiting many of today’s aerospace assembly needs. Consistent torque on each fastener installed is achieved through the integrated functions of the system working together.
What are the features of Hi Lok collars?
Collars’ wrenching element is designed to break-away at a controlled preload. It has been tested over time and has proven its reliability when installed with non-torque-controlled tools. Features. Wide variety of materials and coatings for installation in all structures
What are the different types of Hi Shear fasteners?
The fasteners are available in different head styles, such as flush shear, protruding shear, flush tension and protruding tension. Collar styles include the standard size as well as oversize, sealing, swage and self-aligning.
How does the Hi Lok collar work on a jet Tek?
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.
