The RYOBI 660419003 is an OEM M3.5x26mm machine screw used to secure internal and external components in RYOBI and RIDGID power tools. This fastener maintains structural integrity across the assembly, keeping housings, guards, and mechanical subcomponents properly seated during operation. As a genuine OEM part, it is manufactured to the original dimensional and thread specifications, ensuring correct fit without modification. Licensed power tool technicians and service shop mechanics install this part during routine maintenance, component replacement, or post-repair reassembly.
This screw applies to RYOBI and RIDGID power tool models that call for an M3.5x26mm fastener at the designated mounting point. It is appropriate for both shop repair facilities and field service technicians performing warranty or out-of-warranty tool repairs. Consult the specific tool service manual or parts diagram to confirm this is the correct fastener for the assembly position being serviced.
Designed as an OEM replacement screw for RYOBI and RIDGID power tools requiring an M3.5x26mm fastener. Refer to the tool parts diagram or service manual to confirm fitment for the specific model being serviced.
Power tool service technicians should disconnect the tool from all power sources and remove the battery pack before beginning any fastener replacement. Use a properly sized screwdriver or bit to avoid stripping the head. Do not overtighten, as M3.5 fasteners in plastic or lightweight housings are susceptible to thread damage under excess torque. Follow the tool manufacturer service documentation for correct assembly sequence.
