Security Stud for Hinges

Security Stud for Hinges

Product Information & Specifications

  • Security studs are used for exterior doors that open outward. Doors that open outward have their hinge pins on the outside of the building.
  • If a potential intruder removes the hinge pins, the security stud protects the door from being removed by locking the leaves of the hinges together.
  • To install the security studs, remove two screws from your hinge. These two screws must be aligned back to back when the hinge (or door) is closed.
  • Replace one of the screws with a security stud and drill a receiving hole in the other empty screwhole
  • When the door closes the security stud will slide into the receiving hole locking the two hinge leaves in place
  • Security studs are available to fit a #10 screwhole and a #12 screw hole
  • To determine your screw hole size it is best to take a countersunk screw with a known size and place it in the hinge screw hole.
  • A #10 countersunk head screw measures 11/32" across the head. A #12 countersunk head screw measures 3/8" across the head.
  • The larger studs (SKU 309250 and SKU 309252) are threaded with a 12-24 machine screw thread which matches the thread that is used on metal door frames. Both size studs will work on wood doors and frames.
  • They are sold by the pair (two studs)
