The INGERSOLL 2161-638 is a backcap bolt designed as a replacement fastener component for Ingersoll Rand power tools. Backcap bolts secure the rear cap assembly to the tool housing, maintaining structural integrity under the repeated torque and vibration loads common in pneumatic and power tool applications. This part is sourced from the Ingersoll Rand parts and accessories line and is intended for use by qualified technicians performing tool service, rebuild, or maintenance work.
This backcap bolt is used in power tool repair and reconditioning applications. It is a direct service replacement part suited for shop environments, assembly lines, and field service settings where Ingersoll Rand power tools are maintained and repaired. Installation is typically performed by tool service technicians during disassembly and rebuild of the rear cap or housing assembly.
Designed as an OEM-style replacement fastener for compatible Ingersoll Rand power tools requiring the backcap bolt component during service or rebuild.
Installation should be performed by a qualified tool service technician familiar with Ingersoll Rand power tool disassembly procedures. Disconnect and de-energize or depressurize the tool completely before beginning any service work. Use appropriate hand tools and follow the manufacturer service documentation for proper assembly sequence and fastener seating. Inspect surrounding housing components for wear or damage before reinstalling the backcap assembly.
