High Strength Stainless Stee...
The special characteristic of Aerospace products include high strength and corrosion resistance.
These help to withstand high pressure (for eg, while exiting earth’s atmosphere) and higher temperature (for eg, exposure to burning rocket fuel).
High Strength Stainless Steel Fasteners: A2-80 and A4-80
A2-80 and A4-80 combine the high mechanical strength with corrosion resistance for an effective solution to many situations.
These are very useful for Aerospace applications as they allow the designer to reduce weight of the fastener for a joint.
Higher mechanical strength as compared to standard A2 / A4 is achieved through the cold-drawing process, providing a minimum Ultimate Tensile Strength of 800 MPa.
For most Aerospace, Petro-chemical and Offshore applications, SS-316 A4 is the preferred choice.
Unlike 304, 316 stainless steel has a higher nickel composition and contains a relatively high amount of molybdenum, whereas the 304 stainless steel does not contain molybdenum at all. This differences provides 316 stainless steel (or A4 stainless steel) a significantly greater corrosion resistance. This corrosion resistance specifically denotes A4 stainless steel with the ability to resist acids and salts, making it a great solution for research, chemical engineering and marine applications, amongst many others.
Designers and Engineers may find value in this extra corrosions resistance, especially if replacement or maintenance costs are relatively high, such as on tall buildings, installations that may experience any sort of salt spray or underwater applications, or simply for creating longer lasting lab or engineering equipment that may be subject to acidic or salty conditions.
Additionally if mechanical properties are also a concern for the material?
For equipment that is moving or having to withstand significant mechanical strain, then having a higher class stainless steel will also improve the life of the fastener, thereby reducing MRO costs and possible down time.
In such situations, the A4-80 range of fasteners are the best option that provides high corrosion resistance along with high mechanical strength.

Low Head Torx Machine Screws...
The notion of a drive with hexalobular sockets are a decisive step in developing drives better adapted to manual and automated assembly. This drive is becoming increasingly popular throughout the world.
Low head socket cap screws are designed to be used in special applications where head height clearance is a problem. Because of their reduced head height and smaller socket size, they normally cannot be pre-loaded as high as a standard socket head cap screw and should not be subjected to high dynamic loads.
Suitable for use in parts too thin for standard height socket cap screw and for applications with limited clearances.Available with Hexagonal Socket Head and 6-Lobe (ISO-14580) Socket Head for more reliability.

Carriage Bolts
We offer a wide range of metal bolts and studs. What is the difference between screws and bolts?
Bolts can be described as long shafts with a distinct head on one side. These are generally partially threaded. A fully threaded bolt is referred to as a screw.
Square Neck Carriage Bolts
This is known by different names such as Carriage Bolts, Coach bolts/ Round Head Square neck bolt, Mushroom Head Square neck bolt etc. Useful for fastening wood and metal together.
It is distinguished from other bolts by its shallow mushroom head followed by a square neck, while the shank cross section of the bolt is circular.
This gives the bolt its self locking feature. The square neck grips into the part being fixed preventing the head from turning when the nut is tightened.
Standard – DIN 603

Tri-Lobe Thread Forming PAN ...
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.

Allen CSK
Flat head screws are used for flush mounting of sections, usually where one part slides over another or one part is mounted on another. Countersunk head screws, like button heads and low heads, are limited by configuration in their tensile strength capability. Because of this, they should not be used in applications requiring full strength, where Socket Head Cap Screws should be used.
The head angle for metric countersunk socket screws is 90 degrees up to & including M20 and 60 degrees over M20. The head angle for Imperial is different – Unified is 82 degrees and British thread forms are 90 degrees.
Usage : Machine Guards, Hinges, Covers, multiple level assemblies etc.
Available in Hexagonal socket drive and the improved 6-Lobe (Hexalobular) drive.
Allen (Hex socket) Flat Head Screws are available as per ISO 10642 (similar to DIN 7991 which is now obsolete).

Flange Bolts
We offer a wide range of metal bolts and studs. What is the difference between screws and bolts?
Bolts can be described as long shafts with a distinct head on one side. These are generally partially threaded. A fully threaded bolt is referred to as a screw.
Flange Bolts
Flange bolts, also called Hex Flange Screws, are a special type of bolt which have a flange below its head. They look like a bolt with a washer attached to the head.
The flange provides a more even distribution of the load. Flange bolts eliminate the need to use a washer giving higher flexibility in a wide range of operations.
Standard – DIN 6921.
Materials – Mild Steel and Stainless Steel.

Allen Button Head BHCS
The Socket Button Head Screw design as per ISO 7380-1 is primarily used where a lower profile head is required and for aesthetical reasons.
Button head socket cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face.
Compared to a standard socket head cap screw, button heads have a lower and wider profile which can be useful when the clamping material is too thin to counter-bore.
A button head socket cap screw’s large diameter face also helps to distribute force more evenly. They are also known as Button Head Cap Screws or BHCS.
These screws can take a lower tightening torque as compared to the DIN 912 screws.
Hence, these screws are not recommended for high demand applications.
Available in Hexagonal Socket drive and 6-Lobe (Hexalobular) drive for higher reliability.
