Hi-Lok Installation Tools

Hi-Lok Installation Tools

Unique aircraft fasteners require specialized tooling for proper installation. Hi-Lok Installation tools From EUMRO Aircraft Tools include assemblies, box ratchets, hand ratchets, grip scales, hex keys, protrusion gauges, roller ratchets and installation sockets.

We are particularly adept at tools used for Broached Pin installation. This includes Hi-Lok, Hi-Lite, Hi-Tigue, and Torque Controlled fasteners.

We feature the Omega brand, which also produces gauges to determine the correct fastener length for a hole and to check the pin protrusion of the completed installation.

Hi-Lok Assembly Kits from Omega are a hand tool assembly for the installation of the Hi-Lok or Hi-Lite fastening systems. Hi-Lok Assemblies include a hand ratchet wrench with a through hole, an installation socket and a plastic handle Allen Wrench.
Box Ratchets
Hi-Lok Box Ratchets are perfect for installing Hi-Lok fasteners. Our Hi-Lok Box Ratchets are made of high quality, heat-treated steel and finished with a nickel-chrome plating. The result of this process are durable, long-lasting aircraft tools.
Grip Scales
Hi-Lok Grip Scales From EUMRO Aircraft Tools serve two purposes. The thicker side measures 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.
Hand Ratchets
Hi-Lok Hand Ratchets are manufactured from high quality materials and nickel-plated for durability. These hand ratchets are available in a wide variety of sizes and are suited for a wide range of installations, including Hi-Lok systems
Hex Keys
Hi-Lok hex keys, Hi-Lok hex key kits and Hi-Lok hex key replacement bits from Omega. Our high quality hand ratchets designed for use when installing Hi-Lok style fasteners or other hand-tool applications. Omega also offers replacement tips.
Protrusion Gauges
Pin Protrusion Gauges are manufactured for use on all types of frangible and torque-control fasteners. These gauges determine if the correct length pin has been installed by determining if the pins projection is between allowable minimum/maximum range.
Roller Ratchets
Hi-Lok Roller Ratchets were developed in response to the need in the aviation industry for very small ratchet wrenches that could be used in extremely tight spaces on aircraft where handle 'swing' was limited by obstructions, increasing functionality.
Anti-FOD Hi-Lok Installation Sockets are manufactured to fit conventional square drives. Our Hi-Lok Installation Socket feature a generous through-hole to enable the use of hex keys when necessary for Hi-Lok, Hi-Lite, and Hi-Tigue installations.
Tight-Squeeze Hand Tool
The unique ''Tight-Squeeze'' is a full function hand tool for Hi-Lok fastener installation. This amazing tool does just what the name implies. It gets into tight places, and allows One-Handed Hi-Lok installation. Works for all collars.
