Fastener Innovation Alley
扣件新品大道compiled by Fastener WorldYellow Trivalent Chromate Plating 黃色三價鉻酸鹽電鍍At present, trivalent chromates include chromates, unichromates and black variants (chromates are silver white), but they have neverappeared yellow like hexavalent chromates. In the past, hexavalent chromium plating was mostly used for yellow colored products.
However, in light of the global environmental issues, Heiwa Kaken fromJapan has developed a surface treatment technology that can give ayellow or red color like hexavalent chromate does, even on trivalentproducts.

Characteristics of Trivalent Yellow* Giving a yellow or red interference color as hexavalent chromate does!
* Corrosion resistance is equivalent to trivalent chromate: 72 hours
without white rust, 120 hours without red rust!
* No hexavalent dissolution will be detected!
* Together with trivalent chromate, it can be used to distinguish minor
differences in size and threads.

TriLead Crack-free Woodworking Screw「TriLead」木工螺絲The patent-pending TriLead screw, with a special bit shape newly
developed by SYNEGIC, can cut wood and discharge wood chips to perfectly drill into MDF or particle boards without cracking thewood or creating burrs during the drilling process. There is no need to drill holes in the wood before use. TriLead screw adopts chromate
surface treatment, and can be used with hexagonal bits, suitable for wood with the thickness of 10-20mm, including shelves and otherhousehold furniture.

Kwik-X 錨固系統
Hilti North America, a global leader providing innovative
tools, technology, software, and services to the commercial
construction industry, introduces the Kwik-X Dual Action Anchorsystem, the first of its kind on the market, combining the highperformance of adhesive anchors and installation speed andsimplicity of screw anchors. Reducing multiple steps in thetraditional adhesive anchor installation process, Kwik-X reduces
costly man hours and jobsite expenses. Kwik-X can reduce
installation time by up to 70% and save up to 20% in total cost of installation when compared to traditional adhesive anchoringsystems. “Contractors can save time and money by reducing the complexity of installation with the Kwik-X. Leading up to a 4x fasterinstallation over traditional adhesive anchors and combined with Hilti’s industry-leading expertise, thereby reducing labor costs andhelping deliver peace of mind to a jobsite,” said Rafael Santos, Senior Director of the Hilti North America Fastening and ProtectionBusiness. Comprised of the convenient Kwik-X pre-portioned adhesive capsule and Kwik HUS-EZ screw anchor, the system provides
the necessary performance for safety-critical applications. It reduces the number of steps in the installation process, such as holecleaning, curing time, and dispensing – eliminating adhesive waste and the need for accessories like brushes, air compressors, anddispensers. This simplicity results in increased productivity by reducing the risk of human error. Additional features such as highperformance in real jobsite conditions and the capability to remove and reinstall the anchor in the same borehole help cater to theneeds of the installer. These factors help save contractors' time and money.

Cross Drive Recess for Bits ofSimilar Sizes
共用起子頭的十字溝「Share Cross」
In manual fastening and loosening of screws atconstruction sites and other workplaces, it is timeconsuming to change bits for each screw drive recess, whichcauses users to disassemble and assemble with a bit that does
not fit the recess, thus resulting in a collapsed recess.
To solve this problem, Nitto Seiko from Japan has developed “Share Cross” that can be used with bits of similar
sizes. “Share Cross” can be suited for various types of fastening and improves work efficiency in manufacturing
operations.
“Share Cross” is a small cross-recess with another large cross-recess superimposed on it, so that bits of similar
sizes (e.g., #2 or # 3) can be used on the same screw head recess. The structure is such that the drive surfaces fortransmitting torque can be shared, which achieves the optimum fit of the bit and maximizes the performance.

High Toughness
Tempered Silver Bright
Steel for Wind Turbine
Fasteners
高強韌風電扣件
用調質銀亮鋼(China)XingCheng Special Steel’s
research team has researched anddeveloped grade 10.9 40M+QT highstrength tempered silver-bright steel
for wind turbine fasteners with amaximum diameter of 80mm. The newproduct was successfully researchedand developed by the scientific researchteam of XingCheng Special Steel incooperation with Gamesa, Siemens
and Vestas, the world’s leading windturbine manufacturers, after precise
control of smelting, continuous casting,continuous rolling, continuous heat
treatment, silver-bright processing andother manufacturing processes.
It replaces the traditional
34CrNiMo6 high Ni steel, and theheat treatment process is exclusively
produced in a natural gas heatedcontinuous furnace. The quenching
medium uses water to replace thetraditional oil and soluble medium,
which meets the requirements ofhardened core organization, ultralow hardness difference distribution
in the whole cross-section, andoptimal matching of high strengthand toughness for the needs of highend large fasteners, achieving green,energy-saving, and environmentallyfriendly manufacturing.

New Fastener Accessory for Threaded
Holes (NJD-2506)
用於螺紋孔的新型扣件配件“I’m a contractor and I wanted to create a new fastener accessory
that can be used when re-inserting a screw in a damaged threadedhole,” 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 to help secure loose screws
in wood with applications including cabinets, door hinges, andstrikeplates. 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 and re-thread a hole. The invention
features a practical design that is easy to install and use so it is ideal
for contractors and do-it-yourselfers.
The original design was submitted to the New Jersey sales officeof InventHelp. It is currently available for licensing or sale tomanufacturers or marketers.

TAKECOAT-1000「竹塗料-1000」

Oxidation Colored Stainless Steel Screws
不銹鋼氧化著色螺絲
Ikeda Metal Industrial from Japan has developed stainless steelscrews colored blue, yellow or red by oxidation coloring treatment.
These screws are designed to help operators detect foreign substancecontamination at food production sites early and prevent shipping
contaminated products. Stainless steel screws are commonly usedin the assembly of food manufacturing machinery because of theircorrosion resistance, but they can be difficult to locate if they
become loose and fall off and get mixed with milk, mayonnaise
or other white colored foods. In fact, there have been cases wherepackaging was mixed with screws and shipped unknowingly.
To solve this problem, Ikeda Metal Industrial designed a special
surface treatment called “stainless steel oxidation coloring” forcoloring stainless steel screws to comply with the Food Sanitation
Law. By easily identifying the color of the screws, even if it is mixed
with food, it is possible to detect foreign substance contamination
at an early stage and prevent shipping products from mixing withother substances.

“TAKECOAT” developed byTAKENAKA SEISAKUSHO
from Japan is claimed to take thehighest share in the fluorocarbon
polymer market globally. It can provide
excellent rust and corrosion resistancein harsh environments such as in the seaand desert. It has 6-times the durabilityof hot-dip galvanizing as tested in a salt
spray test.

TAKECOAT® -1000 has a two-layer
structure of fluorocarbon polymer as theupper film and a special under-treatment
layer. Combined with a special treatment
technology, the thin films are excellent incorrosion and rust resistance and have highlubricity, suited for fasteners. TAKECOAT has
been used on bolts and metal parts used onbridges, insert pipes, marine
structures and oil refineries.
