Dewalt 180312 Contact Arm Spring

Product Description

The DEWALT 180312 is a contact arm spring designed as a direct OEM replacement component for DEWALT power tools. The contact arm spring provides the tension necessary for the contact arm mechanism to function correctly, ensuring consistent actuation and reliable tool operation. This type of internal spring component is typically serviced by tool repair technicians and experienced tradespeople performing bench-level repairs on nailers and fastening tools. Replacing a worn or broken contact arm spring restores proper sequential or bump-fire actuation to the tool.

The 180312 contact arm spring is used in DEWALT power tools that rely on a contact arm safety mechanism, most commonly pneumatic nailers and similar fastening equipment used in framing, finish carpentry, roofing, and general construction applications. It is a service part intended for repair and maintenance of existing tools rather than new assembly.

Installation Notes

Installation should be performed by a qualified tool repair technician familiar with pneumatic nailer disassembly and reassembly procedures. Disconnect all air supply and remove any fasteners from the tool magazine before beginning service. Small internal springs can be under tension during disassembly — use appropriate hand tools and eye protection throughout the repair process. Refer to the DEWALT service manual for your specific tool model for correct assembly sequence and torque guidance.
