Deltana PIN-ST35 Pin for 3-1/2" x 3-1/2" Steel Hinges

Yes, and that is the usual reason to buy one. If the hinge leaves and knuckles are sound and only the pin is missing, bent, or the wrong finish, a replacement pin puts the door back in service without pulling the hinge off the frame. Match the pin to the hinge size first, the PIN-ST35 is dimensioned for a 3-1/2 x 3-1/2 inch steel hinge at 3-5/8 inches long by 1/4 inch diameter. If the knuckle barrel takes a different diameter, the pin either drops through or will not start.

No. The PIN-ST35 is a standard loose pin for a 3-1/2 inch steel hinge, it drops in and taps out. On an outswing exterior door where the hinge barrel is on the outside, a plain loose pin means the door can be lifted off by anyone with a screwdriver. For those openings a locksmith would specify a hinge with a non-removable pin feature or set screw, or add a security stud set, rather than a replacement loose pin.

Nine finishes, meant to match the steel hinge they go into: Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, Brushed Brass, and Antique Brass. For a property manager patching hinges across a building, order the pin in the finish already on the door rather than the finish name on the box of hinges you bought last year, plating names drift between runs.

One. The PIN-ST35 is sold each, one pin per unit, so a door on three hinges needs three pins ordered. Buy a spare or two if you are pulling pins on an older opening, a bent or mushroomed pin is usually why the pin is coming out in the first place.

Tap the old pin out from the bottom and measure it, or measure the barrel bore. The PIN-ST35 runs 1/4 inch in diameter and 3-5/8 inches long. Standard residential and light commercial 3-1/2 inch steel butt hinges are built around that pin size, but plain bearing, ball bearing, and spring hinges in the same nominal size can differ, so the old pin is the only measurement worth trusting.

Steel through the body, with the finish plated over it. That matters on a door that gets swung hard, an entry or a corridor door in a multi-family building, where a soft pin walks up out of the knuckle over time. The finish is there to match the hinge, not to carry the load.

Handing does not apply to the pin. A butt hinge pin drops through the knuckle from the top on either hand, so the same PIN-ST35 works on a left or right hand door. What does matter is which end is up, install with the head at the top so gravity keeps the pin seated.
