QTF-1

1" OD Quarter-Turn Panel Fastener - sometimes called Ring Latches or Cam Latches - Here is a breakdown of the features that identify them:
* The Ring Handle: This allows the fastener to be operated by hand without a screwdriver. You lift the ring to turn the latch.
* The "T-Pin" (Crossbar): Look closely at the tip of the shaft (especially on the bottom right and bottom left pieces). Instead of a screw thread, there is a small metal crossbar. This is designed to fit into a slotted "keyhole" opening.
* The Plastic Washer: The white/clear washer (visible on the bottom left piece) acts as a spring. When you lock the fastener, this washer compresses, creating tension to prevent the latch from wiggling loose due to vibration.
How they work:
* The pin is inserted into a slot on the machine's frame.
* You turn the ring 90 degrees (a "quarter turn").
* The "T" shape rotates behind the frame, locking the panel in place.
Common Uses:
* Electronics Enclosures: Securing the metal box around VCRs, old computers, or industrial controllers.
* Machinery Covers: Holding access panels shut on printers or copiers (so a technician can open them quickly).
* Portable Cases: Latches for sewing machine covers or instrument cases.
They are essentially "quick-release" screws that don't require tools
