Part 520-035 is a screw set containing multiple fasteners used to assemble various components of the spray gun. The set includes screws for securing handles, guards, retaining plates, and other attachments. When original screws become stripped, corroded, or lost, replacing the complete set restores secure assembly and reliable gun operation on compatible units.

The 520-035 Screw Set is a collection of threaded fasteners designed for use across multiple airless spray gun models, including the Airless SGX 20, Airless S5, and Airless G-15 XL Gun. This set provides the correct screws for securing various components that may require replacement during routine maintenance or repair. Typical applications for these screws include attaching the trigger guard to the gun body, securing handle grips or cover plates, mounting the fluid inlet fitting, and fastening retaining plates that hold internal valve components. Each screw in the set is manufactured to the precise thread pitch, length, head style, and material specification required for its specific location on the spray gun. Over the service life of the equipment, individual screws can be lost during disassembly, stripped through overtightening, or damaged by corrosion from exposure to paints and solvents. The screw head drive feature may become worn, making removal or tightening impossible. Using an incorrect screw from hardware stock can lead to several problems: wrong thread pitch can damage the gun body threads, incorrect length may bottom out or fail to engage fully, improper head style may not fit the recessed cavity, and wrong material may corrode or fail under vibration. The screw set solves these issues by providing all the fasteners needed for a complete reassembly in one convenient package. Having the correct screws on hand during service reduces downtime and ensures that each component is secured with the proper fastener. Replacing worn or missing screws with the correct set restores secure attachment, maintains proper alignment of components, and prevents loosening under the vibration of normal spraying operations. This is particularly important for safety-related components such as trigger guards, which must remain firmly attached to prevent accidental triggering.
