Schlage C504-116 – Frequently Asked Questions

1) Which Schlage cylinders does the C504-116 check spring pin work with?
The C504-116 check spring pin is made for Schlage Everest and Everest 29 Small Format Interchangeable Core (SFIC) cylinders. It is a genuine Schlage part that drops into those cores without modification. It is not intended for conventional Schlage C keyway cylinders or large format cores.
2) How many check spring pins come in a pack of Schlage C504-116?
They ship 100 to a package. That is a bench quantity aimed at a locksmith or maintenance shop rebuilding or re-pinning Everest and Everest 29 SFIC cores in volume, not a one-off repair part.
3) Can a Corbin Russwin swivel spindle pin be used in place of the Schlage C504-116 check spring pin?
No. The Schlage C504-116 is a check spring pin that sits inside Everest and Everest 29 Small Format Interchangeable Core cylinders, providing spring tension for pin tumbler alignment and key operation. The Corbin Russwin 499F838 is a swivel spindle pin with set screw, a knob and lever spindle retention part for doors 1-3/4 inches thick. They serve different assemblies entirely: one is a cylinder internal, the other is a trim and spindle fastener. Order the C504-116 when you are rebuilding or repinning a Schlage SFIC core.
4) What does the check spring pin actually do inside an SFIC core?
It supplies the spring tension that keeps the pin tumbler stack seated and returning properly, so the key turns smoothly and the core relocks. If a core is sticking, keying erratically, or a pin stack is not returning after a key pull, a failed or fatigued check spring pin is one of the parts you replace during a rebuild.
5) Can I use an aftermarket spring instead of the genuine Schlage C504-116?
Stick with the Schlage part if you are servicing an Everest or Everest 29 SFIC core. The C504-116 is the factory component built to Schlage's tolerances so it seats correctly in the core housing; substituting a spring with different tension or length is how a re-pinned master keyed core ends up with a key that drags or a core that will not relock in the housing.
6) Do I need anything else to rebuild a Schlage Everest SFIC core besides the C504-116?
The C504-116 covers only the check spring pin. A full Everest or Everest 29 SFIC rebuild also needs the bottom, master, and top pins in the depths your keying calls for, plus the control and operating key cuts to match your system. Order the spring pins alongside the pin kit for the same Everest platform so the stack heights stay correct.
7) Is the Schlage C504-116 spring pin rated for commercial use or is it a residential part?
Commercial. Schlage classes the C504-116 as a commercial mechanical lock component, which matches where SFIC master key systems actually live: offices, schools, hospitals, and government buildings on master keyed hardware.
