When designing structural connections between dissimilar metals, attention must be paid to galvanic reaction. If hardened-steel parts such as self-drilling screws are used for the connection, hydrogen assisted stress corrosion cracking is also a possibility.

Flex Technology fasteners with corrosion-preventative coating can avoid these dangers and protect the integrity of the structure. In exterior applications or aggressive interior environments, bi-metallic or super alloy fasteners are recommended.

For use in critical and dissimilar metal applications, windows, doors, curtain wall systems and solar panel racking systems to prevent fastener failure, the Flex Technology family of products surpasses any standard fastening format available.

The inwards-facing lips on the open side of strut channel are used to mount channel nuts, braces, connecting angles, and other types of fittings to join lengths of strut channel together or to connect pipes, wire, threaded rod, bolts, or walls into the strut channel structural system.

The most popular strut channel sizes are 1 5/8” x 1 5/8″ and 1-5/8” x 13/16. The material used to form the channel is typically 12 gauge or 14 gauge thick sheet metal. Several variations are available with different hole patterns for mounting to walls and supports. Solid channel has no holes predrilled, and must be drilled on site. Punched channel has round holes, large enough for threaded steel rod or bolts, punched in the top of the channel at regular 1 7/8 inch centers. Half-slot channel has short, rounded end rectangular slots punched out on 2” centers. Slot channel has longer slots on 4” centers.

To form stronger structural elements, shapes are manufactured with two lengths welded together back to back, or three or four welded together in various patterns Strut is mostly manufactured out of sheet steel with electro plated, perma-gold, pregalvanized and hot dip galvanized coatings. Strut channels is also manufactured from stainless steel or aluminum alloy, in cases where rusting might become a problem or where weight is an issue.

The Smart DI+ is an all steel internally threaded anchor specifically designed with  safety, reliability and speed in mind. The patented Smart DI+ design reduces the amount of force required to set the anchor. What used to take approximately twenty hammer blows on a typical 3/8″ diameter part can now be accomplished in approximately 5 blows, reducing overall labor costs by approximately 50%. The cylindrical plug design concentrates more expansion at the bottom of the anchor where it’s needed to maximize performance.

Mechanical contractors and electrical contractors use drop-in style anchors to hang threaded rod from ceilings to run pipe supports, fire sprinklers, cable trays and strut. Concrete contractors use them for temporary form work. With the added feature that allows a contractor, general foreman or inspector to see if the anchor has been set, Smart DI+TM drop-in is not only easy to set but safer than conventional drop-in anchors.

Smart DI+  Drop-In has the highest safety rating in its class. That not only makes the choice smart, but easy!

Easy to use:
1. Drill the hole with Smart DI+ Bit
2. Lock on the Smart DI+ setting tool
3. Drive the plug with the same tool used to drill the anchor hole

Smart DI+ Drop-in Anchors are now in stock and ready for delivery.

Let’s use a common code description and break it down, we’ll use ABL6-8A as our example.

The first letter “A” indicates the rivet material. For instance, “A” for aluminum, “S” for steel, “C” for copper and “SS” for stainless steel.

The second letter tells us the head style, “B” for button head, “C” for countersunk.

If there’s a third letter in the description, it’ll be an “L” for large flange head.

The first number in the description is for body diameter, in 32nds.

The second number indicates maximum grip length in 16ths. Grip Range is the “working range” that the rivet can handle to meet the strengths designated in the IFI 114 Standards. Grip Range is not actual length. As a general rule, you would want to subtract 1/8″ off the length of the barrel for the barrel to be able to expand and lock the material together. So using your math skills and reducing 8/16″ to 1/2″ and subtracting 1/8″ you would have a grip range of 3/8″ and your rivet would have a size of 6-8.

The final letter is the mandrel (nail or stem} material. “A” for aluminum, “S” for stainless steel, “B” for brass, “C” for copper. No letter indicates a steel mandrel.

The body of the blind rivet is inserted in a hole in the materials to be joined or the blind rivet is placed into an installation tool, and then inserted into the application.

Activate the tool by squeezing the trigger in an air/hydraulic tool or the handles in a manual tool. The tool pulls the mandrel, drawing the mandrel head into the blind end of the rivet body. This action forms an upset head on the rivet body and securely clamps the application materials together.

The mandrel then reaches its predetermined break-load and will snap, with the spent portion of the mandrel breaking away and being removed from the “set” blind rivet.

Blind rivets are available in a range of body styles such as open, closed end, and multi-grip, with head styles in button, countersunk and large flange and in materials such as aluminum, steel, copper, plastic and stainless steel.

Fast, easy-to-use blind rivets offer speed of assembly, consistent mechanical performance and excellent installed appearance, making blind riveting a reliable and economical assembly method.

1) Metal Devil® metal cutting circular saw blades are engineered to use dry cut technology.  That means you do not need to use lubricant or coolant with the Metal Devil blades.

2) These blades perform best when used with low RPM metal cutting saws, such as the Morse Metal Devil 7, 9 and 14 inch saws.

3) Select the correct blade design for your application to achieve the best performance, such as a steel, thin steel or aluminum blade.

4) Clamp your material securely so that it does not vibrate or spin. Morse offers a V-block clamp for tubes.

5) Extend the blade completely out of the saw and use a guide or straight edge to make the cut.

6) Bring the blade to full speed before entering the cut and do not push the saw through the material. Slow down and let the teeth make the cut.

Consistently follow these steps to optimize your blade life.

Happy Sawing –

#1. The shear and tensile strength of the blind rivet selected and the number of blind rivets used in the application should equal or exceed the joint strength requirements.

#2. The blind rivet body material should be compatible with the materials to be joined to resist galvanic corrosion that may result in reduction of joint strength. If dissimilar materials are widely separated on the galvanic chart, it is advisable to separate them with a dielectric material such as paint or other coating.

#3. The total thickness of materials to be joined must be considered. Select the rivet “grip range” which includes the total thickness of materials to be joined.

#4. Use recommended hole sizes for each blind rivet. An undersize hole will not allow insertion of rivet body and an oversize hole may cause rivet failure, joint failure and could adversely affect rivet shear and tensile strengths.

#5. Various head styles are offered to accommodate different assembly needs. The most popular is the button head, whose lower-profile head is twice the diameter of the rivet body. This provides adequate bearing surface for nearly all applications. The large flange rivet provides greater bearing surface for fastening soft or brittle facing materials. The countersunk head rivet is available for applications where a flush appearance is required.

Rivet nuts offer many benefits over nuts, bolts, weld nuts, self-tapping screws and pressed inserts, primarily their faster assembly and lower installation costs. Rivet nuts are assembled “blind” from one side only, ideal for assembly of box, tube, extrusions, or closed sections. Rivet nut installation is very efficient by using easy-to-operate, inexpensive, lightweight hand tools or handheld powerful air/hydraulic setting tools. Rivet nuts install into a wide range of material thicknesses due to their wide grip range tolerance.

A rivet nut is applied strictly as a mechanical fastener with minimal deformation of the work-piece and no damage to pre-painted surface coatings. Installation is environmentally friendly and produces no harmful gasses, heat, dust or electromagnetic fields to affect workers.
