A window spring bolt is a type of locking mechanism that is used to secure a window in place at different elevations. It typically consists of a metal spring bolt that is attached to the window sash that engages into the apposing sash to keep the window in predetermined amounts of opening.

When the window is closed, the bolt can be extended to engage with apposing drilled hole, holding the window firmly in place and preventing it from being opened from the outside. The spring-loaded bolt allows the bolt to be easily released when the window needs to be opened.

Window spring bolts are commonly used in residential and commercial buildings as an additional security measure to help prevent break-ins or unauthorized access. They can be installed on various types of windows, including sliding windows, double-hung windows. Window spring bolts can also be uses to hold wood framed screens into the window frame.

I have a hinge that I am trying to replace but I need help identifying it. Can you help?

Yes! Please click here to visit our Hinge Finder page.

Some of your hinges are sold by the each and some sell by the pair. What is the difference?

When the unit of measure says “pair” that means two hinges. Usually you need one pair of hinges per door. When the unit of measure says “each” that means one hinge. You would usually order 2 “each” hinges per door.

I want to replace my hinges. How do I make sure the screw holes on the new hinge match the screw holes on the old hinge so I do not have to redrill the holes?

Unfortunately, hinge manufacturers have never standardized the location of their screw hole patterns. Every manufacturer puts their screw holes in a slightly different place. This means that when you replace hinges you will almost certainly have to do some filling and redrilling. The exception to this is Architectural door hinges which are built to a standardized template for each size hinge.
