Disruptive Sealing
Technology by JPB Système
The 5mm Smart Washer is a disruptive
smaller-sized smart washer sealing technologythat improves MRO efficiencies by reducing
t he need to ma nually check t he torquelevel because of the touchless and wirelessmeasurement of bolt axial load.

"I'm a contractor and I wanted to create a
new fastener accessory that can be used when reinserting a screw in a damaged threaded hole," said
an inventor, from Milltown, N.J., "so I invented theNO MORE LOOSE SCREWS. My design would
increase friction, allowing you to effortlessly drive
the screw into the threaded hole."
The invention provides an effective way tohelp secure loose screws in wood with applications
including cabinets, door hinges, and strikeplates. In
doing so, it eliminates the spinning issues associatedwith damaged threads. As a result, it increases
efficiency and it eliminates the need to re-drill andre-thread a hole. The invention features a practicaldesign that is easy to install and use so it is ideal forcontractors and do-it-yourselfers.
The original design was submitted to the New
Jersey sales office of InventHelp. It is currently
available for licensing or sale to manufacturers ormarketers.

The thickness of the washer has been
reduced by more than one-third. JPB Systèmefrom France has leveraged improvements instrain gauge technology to develop a smaller Smart Washer variant that is mucheasier to integrate and retrofit while delivering the same functional benefits as
its larger counterpart. The smaller size of the washer allows for it to be used
across an increased number of areas within the aircraft, whereas the original
7.6mm washer is more suitable to experimental scenarios in on-the-ground test
environments.
The washer uses intelligent connectivity by incorporating a proprietarystrain gauge, as well as a transmission system into the washer, which throughan accompanying reading device (Smart Reader), relays the information tomaintenance engineers. Engineers can be quickly alerted to fasteners that are tootight or too loose and can address them accordingly to limit aircraft downtime.
JPB now allows the engineers to view the percentage of the tension rather
than just the value of the bolt axial load due to the relative measurement whichcalibrates the Smart Washer directly on the customer’s bolt. This has increased
the accuracy of the device from +/- 6% to +/- 2.5%.
The new validated redundancy measurement allows Smart Washer to ‘control’
itself to eliminate incorrect readings in the unlikely event of a software issue. Thisis enabled by doubling the number of measurement points on the washer, whichmeans that upon a false reading, the system immediately alerts the engineer
before taking another measurement from another area of the device.

TAKECOAT-1000 from Japan" TA K E C OAT " d eve l o p e d by TA K E NA K A
SEISAKUSHO from Japan is claimed to take the highest
share in the fluorocarbon polymer market globally. It can
provide excellent rust and corrosion resistance in harshenvironments such as in the sea and desert. It has 6-times thedurability of hot-dip galvanizing as tested in a salt spray test.
TAK ECOAT ® -1000 has a two-layer str ucture off luorocarbon polymer as the upper film and a special
under-treatment layer. Combined with a special treatment
technology, the thin films are excellent in corrosion andrust resistance and have high lubricity, suited for fasteners.
TAKECOAT has been used on bolts and metal parts used onbridges, insert pipes, marine structures and oil refineries.

Share Cross Drive Recess for Bits of SimilarSizes
In manual fastening and loosening of screws at construction sites
and other workplaces, it is time-consuming to change bits for each screw
drive recess, which causes users to disassemble and assemble with a bitthat does not fit the recess, thus resulting in a collapsed recess.
To solve this problem, Japanese Nitto Seiko has developed "Share
Cross" that can be used with bits of similar sizes. "Share Cross" issuited for various types of fastening and improves work efficiency inmanufacturing operations.
"Share Cross" is a small cross-recess with another large cross-recesssuperimposed on it, so that bits of similar sizes (e.g., #2 or # 3) canbe used on the same screw head recess. The structure is such that thedrive surfaces for transmitting torque can be shared, which achieves theoptimum fit of the bit and maximizes the performance.
