Kwikset 1777 Tumbler Springs Pack of 100

Product Description

The KWIKSET 1777 is a pack of 100 tumbler springs designed for use in Kwikset residential pin tumbler lock cylinders. Tumbler springs provide the tension that returns key pins and driver pins to their set positions, maintaining proper cylinder function and key operation. These small but critical components are a standard service part for locksmiths and door hardware technicians performing cylinder rebuilds, rekeying work, or restoring worn lock mechanisms. Each pack ships as a single unit containing 100 springs, making it practical for shops that rekey or service cylinders in volume.

Tumbler springs are consumed during routine cylinder servicing and rekeying operations. This pack is suited for locksmiths, door hardware contractors, and maintenance technicians who stock consumable cylinder components for residential lock service. The springs are sized for Kwikset-standard pin tumbler cylinders commonly found in residential entry, deadbolt, and passage hardware. Having a bulk supply on hand reduces downtime during high-volume rekey jobs or service calls.

Installation Notes

Tumbler spring replacement and cylinder rebuilding is typically performed by licensed locksmiths or qualified door hardware technicians. Before servicing any lock cylinder, remove the cylinder from the door hardware and secure the plug to prevent pin stack components from scattering. Use a plug follower and pin tray to keep components organized during disassembly. Follow applicable local codes and manufacturer service guidelines when servicing residential security hardware.
