Tri-Lobe Thread Forming PAN Screws
Thread-rolling screws form their nut threads themselves when they are screwed into precut holes. This not only saves assembly and production costs, but also creates stable and secure connections.
In contrast to thread cutting, the material structure in the mating thread is not interrupted when threading, but compressed and strain hardened.
The nut threads are automatically formed in cast blind holes, passages or in drilled, lasered or punched sheet metal parts. Especially suitable for materials such as steel, aluminium, brass or copper.
A tri-lobe thread forming screw forms a thread with a machine screw’s thread pitch.
As each lobe of the screw moves through the pilot hole in the nut material, it forms and work hardens the nut thread metal, producing an uninterrupted grain flow.
For use in drilled, punched or cored holes in ductile metals and punch extruded metals without the need for tapping the material thread.
The tri-lobe thread shape enables the threads to form the internal thread. The screw is designed with a tapered point or commonly referred to as lead threads.
The tapered point allows for lower installation torque during initial thread forming. The tri-lobe shape is key to allowing the remaining threads to form threads with the lowest amount of installation torque.
One important thing to note when determining screw length is that the tapered portion of the thread cannot be fully loaded and should not be used to calculate proper screw length.

Unthreaded Spacers
Spacers are fasteners used to connect, separate, or position parts in assemblies.
The hollow body of a spacer is designed to allow the shaft of a screw to pass completely through it before entering the surface material. This forces a gap to be kept between the screw head and the material or component below, while still allowing the fastener to be properly torqued.
They can have a hex or round shape, and are not threaded. They are made of steel, stainless steel, nylon, or aluminum and can have a male or female body style.
They are generally installed over the top of screws to space out or stack circuit boards or paneling. Spacers can be stacked to cover longer screws if needed. Because they are un-threaded and placed over the top of the screw, there is no torque involved. The spacer can spin or twist without affecting the application in which they are used. Also used to calibrate the height of a sensor or switch, or provide heat or electrical isolation.
Heavier Stainless Steel Spacers are commonly use to install lightweight signs or to separate glass tops on a table.
NYLON SPACERS
Nylon is a lightweight, non-conductive material resistant to impact, wear and abrasion. It is ideal for electrical applications or where corrosion is a concern.
These provide sturdy support, alignment and spacing to a variety of applications such as circuit board assemblies, panels and doors.
In the world of electronic components and electronic hardware, these standoffs are typically used to space circuit boards, panels, doors or gears.
A very useful addition to Drone design.
These offer a smooth surface finish that will not erode the insulation of wires that rub against the nylon spacers.
It is also incredibly lightweight for its overall strength, although it can be prone to shearing in high torque installations. While nylon is highly chemical resistant, it is less suitable for use in damp or humid environments, due to its tendency to absorb moisture over time.
Available in Round Body and Hexagonal Body shapes.

Wedge-Lock Washers
Bolted connections tend to work themselves loose under certain operating conditions. Vibrations cause particular problems as they can overpower the “self-locking effect” of bolted connections. This can lead to functional failure or even lead to the connection coming apart. As it’s not always possible to know what forces are acting on the structure, and as constructional measures cannot be implemented everywhere, securing elements are often used.
One of the few effective securing technologies available is the HEICO-LOCK® wedge locking system, the effectiveness of which has been demonstrated by the latest experimental standards (including DIN 65151, DIN 25201-4, NASM 1312-7).FUNCTIONAL PRINCIPLE
Advantages
Certified system for securing bolts, works at low and high preload levels.
Particularly suitable for dynamic loads – including when using lubricants.
Can be re-used.

Wing Screws and Thumb Screws
Wing Screws and Thumb Screws
This is a type of fastener designed to be tightened and loosened by hand rather than needing tools like screwdrivers or wrenches for installation. They have a wide range of useful applications, especially in parts, materials and builds that do not easily support the use of manual or power tools. These can also be useful solutions in a situation where you may need to remove a component or panel regularly. They can make tasks such as maintenance or cleaning much quicker and easier than having to use a driver to remove fully torqued machine screws, bolts, or rivets.
Wing Screws
Wing screws have a wing-like projection from the head of the screw, ideal for
thumb and forefinger leverage in turning.
Ensures rapid assembly and disassembly using only your hand. Wing screws and other hand fasteners are easy to install and make adjustments simple.
They’re ideal for applications where frequent access is require or where tightness needs to be adjusted regularly.
Available in Stainless Steel from M3 to M10.
Thumb Screws
The head of the thumb screw is knurled to provide extra grip and prevent slippage when tightening and loosening. The head diameter of the screw is large for ease of use and also provides a high degree of rotational accuracy.
Thumb screws are available in a shouldered versions known as knurled thumbscrews.
These are widely used in various applications where frequent access, adjustment, or disassembly is required, such as in the field of electronics, computer hardware, automotive, and machinery. Their convenient design enables users to make quick and tool-free adjustments, making them especially valuable in situations where efficiency and convenience are crucial.
Their main use is for fastening down panels, wiring, lids, safety covers, battery compartments, and any other part or component that might need to be removed and reinstalled frequently. They can be used for securing equipment, such as cameras, microphones, and lighting fixtures to stands or tripods, as well as electronic components, such as circuit boards or cooling fans. Thumb screws are also commonly used in HVAC systems for securing ductwork and in automotive industries for holding components in place.
Thumb screws are easy to use, as they do not require any special tools or equipment. To use a thumb screw, turn it clockwise or counterclockwise by applying pressure with your thumb and fingers until the desired tension is achieved. Twist the screw in a clockwise direction to tighten it and counterclockwise to loosen it. If extra force or precision is required, a pair of pliers or tweezers may be used to grip the head of the screw.
