Hillman Fasteners 540147 Compression Spring No. 49 6 Pack

Product Description

The HILLMAN FASTENERS 540147 is a No. 49 compression spring designed for standard compression applications across a wide range of mechanical and structural uses. Built from durable steel, this spring follows a conventional coil compression design that resists axial loads and returns to its original length when force is released. Each package includes 6 springs and ships in a poly bag for easy storage and dispensing on the job. Suitable for maintenance, repair, and light fabrication tasks, this part is a practical stock item for trade professionals who regularly service equipment with spring-loaded mechanisms.

This compression spring fits a broad range of applications in HVAC, plumbing, electrical, and general mechanical service work. Any trade professional who works on spring-loaded components — including damper assemblies, valve mechanisms, latch hardware, or panel fasteners — will find the No. 49 size a useful addition to a service inventory. The 6-pack format reduces the need for frequent reordering and suits both shop stock and field kit replenishment.

Installation Notes

Compression springs should be installed by a qualified technician familiar with the host assembly. Always de-energize or depressurize the system before replacing any spring component. Verify the replacement spring matches the load rating, free length, and coil diameter required by the original application. Use appropriate hand tools and eye protection when compressing or seating springs under load.
