screw post

Aluminum screw posts are also called Chicago screws or Chicago screw posts. They are great for binding all types of products. Screw post can be used for swatches, photo albums, scripts, wine lists, menus, and much more. Screw posts by their nature allow the bound product to be easily updated.
They can even be expanded with the use of screwpost extensions. Screwposts are available brass and aluminum.
Other type of screwpost  is the steel screw post which is recommended for use as an industrial fastener. Steel Screw Posts have a more polished appearance and are heavier duty than our aluminum screw posts. Loose-leaf rings also called hinged split rings or hinged snap rings are great for binding large groups of paper, swatches, and many other items quickly and easily at an affordable cost.

Thread Insert / Self-Tapping Insert

A thread insert also known as a threaded bushing which is a fastener element that is inserted into an object to add a threaded hole. They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material and place a thread on a material too thin to accept it, mold or cast threads into a workpiece thereby eliminating a machining operation, or simplify changeover from unified to metric threads or vice versa.

Self Tapping Inserts (also known as self threaded inserts or Ensats) are cylindrical metal bushings with internal and external threads and are specially designed to cut their own threads as they are being driven into a drilled hole. They provide permanent wear-resistant threads in a wide range of materials, from tough to tap, high strength steels to brittle plastics.

The thread cutting action is performed by the cutting slots on the insert. By tapping its own thread, the self tapping insert eliminates the need for pre-tapped holes.

Feature of  Self-Tapping Threaded Insert: 

• It is easy to installed
• it is designed to replace spring coil.
• It provides strong threads for weak material like aluminum or plactic.
• It is able to install for vibrating environment.

PEM nut / Self-Clinching Nut

PEM nut is a threaded fastener or stand-off that is attached to sheet of metal. They are attached by being pressed with great force so that the end of the nut is expanded in order to stay locked and clinched into the sheet metal

A PEM nut also known  as Self-clinching whcih is an internally threaded fastener, when pressed into ductile metal, displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank of the fastener. A serrated clinching ring prevents the fastener from rotating in the host material once it have been properly inserted. Thus a PEM nut becomes a permanent part of the host material offering strong, load bearing threads in relatively thin sheets of metal.  The generic term for this type of fastener is "self-clinching nut".

(Reference by Wikipedia)

Advantage of Self-Clinching parts:

• Provide strong threads in metal as thin as 0.20"/.51MM
• Maybe installed using any parallel acting squeezing force.
• Provide high pushout and torque-out resistance
• Do not require special hole preparation, such as chamfering and deburring.
• Reverse side of metal sheet remains flush.
• No retapping necessary after application
• Low installed costs.
