Unnamed engineering tools
List of unnamed engineering tools.

Bynar scanner 

This scanning device was used by one of the Bynars aboard the  in 2364, when they worked on the ship's systems. ()

Claw tool 
In 2372, after Neelix discovered that Michael Jonas was secretly working with the Kazon-Nistrim, he attempted to stop Jonas by attacking him with a claw-like tool. ()

Computer hacking tool 
In 2372, after Tom Paris left the USS Voyager and was kidnapped by the Kazon-Nistrim, Paris used a hacking tool to access the systems of the raider he was in to determine the identity of a mole on Voyager. The device also had an explosive which could be timed. ()

Holodeck repair tools 
When the holodeck of the Enterprise-D had malfunctions in 2364, Geordi La Forge, Wesley Crusher, and two technicians used these three engineering tools for diagnostic and repair. ()

O'Brien's toolbox devices 

In 2369, while searching for his missing EJ7 interlock, Chief Miles O'Brien opened his toolbox, which had several tools inside it. ()

Picard's tool 

This tool was used by Captain Jean-Luc Picard in 2063, while doing modifications/repairs on a phaser rifle and talking to Lily Sloane in the observation lounge aboard the . ()

Repair tool 

This repair tool was used by Commander  in 2153 to change the modifications the Tarkalean female made to the ship's avionics control system. ()

Sealing tool 

Neela attempted to use this tool to close a security seal after she finished repairs in the security office. Miles O'Brien told her that this was the wrong tool and she had to use an EJ7 interlock instead, because it was a security seal. ()

Shuttlecraft repair tools 
In 2380, Ensigns Beckett Mariner, Brad Boimler, Sam Rutherford, and D'Vana Tendi used various tools to repair or construct the shuttlecraft Sequoia in one of the ' repair bays. ()

Starship repair tool 
In 2380, Ensign Beckett Mariner handed Ensign Brad Boimler a repair tool for the latter to use on the Sequoia, though he was not seen using it, as a red alert prompted both ensigns to attend their scheduled bridge duty.

That same year, Lieutenant Shaxs used this same type of tool to repair a Romulan Bird-of-Prey that was on display at a Vulcan museum. ()

Subspace transmission scrambler 

This pen-like tool was used by Nog to scramble the subspace transmission between himself and Jake Sisko and the Bajoran Sirco Ch'Ano in 2369. ()

Takret technology 

The Takret Militia brought several pieces of technological equipment aboard the  when they boarded the ship in 2152. Several pieces were placed in engineering in front of the warp injector. ()

Tools aboard Shuttlepod 1 
These tools were used in 2151 aboard  by Malcolm Reed when he was preparing the away mission to the surface of Archer's Comet and the drilling rig. ()

Upgrade tool 

This tool was used by Chief Miles O'Brien in 2372 on Deep Space 9 to double check that the new console he installed in ops, as part of the station's upgrades, was working correctly. ()

Rom later used the same device to perform a com relay bypass in 2373. ()

Warp core utility 

This object was used beside the 's warp core in 2374, while attempting to get it functional again after the ship had Borg modifications installed by Seven of Nine. ()

Warp engine component 

This piece of technology was part of the warp engine aboard the Earth Cargo Service freighter  and damaged during the Nausicaan attack on the ship in August of 2151.

Matthew Ryan brought this piece aboard the Enterprise NX-01. According to Travis Mayweather it was older than chief engineer Trip Tucker and he would get a kick out of this. The quartermaster aboard Enterprise won't have anything like that but engineering should be able to synthesize one. Tucker later told that the valve seals of the piece were shot and he needed about fourty minutes to synthesize new ones while analyzing this piece in his laser micrometer.

When Captain Jonathan Archer later confronted Ryan in his ready room and asked if anything he got from Enterprise was working accordingly, Ryan told him that some of the connections were off by a few microns. ()
