The GRACO 126943 is a fastener specifically designed as a setscrew with a 1/4-20 thread. It is typically used to secure components within GRACO spray equipment, such as the XHF and XHT spray guns, where it helps to hold or adjust internal parts like the spring guide. The material is not explicitly stated in available sources, but similar GRACO setscrews are commonly made from alloy steel with a black oxide finish for corrosion resistance. Key Features: Setscrew 1/4-20 Alloy steel (inferred from similar GRACO and industry-standard setscrews), black oxide finish (inferred) Compatible with GRACO spray equipment, including XHF and XHT spray guns (as referenced in GRACO manuals) Designed for secure fastening and adjustment of internal components Reliable for repeated installation and removal Corrosion-resistant finish (inferred from industry standard) Applications:Used in GRACO spray equipment to secure or adjust internal components such as spring guides and other assemblies. Installation Notes: Using genuine GRACO parts ensures proper fit, function, and safety within GRACO equipment, reducing the risk of equipment failure or malfunction. Loosely thread the setscrew into the designated component (e.g., spring guide) Alternately and evenly tighten the setscrews to the recommended torque (typically 10-15 in-lb or 1.1-1.6 N•m) Ensure the setscrew is fully seated and secure to prevent loosening during operation Use the correct size hex key (typically 1/8" for 1/4-20 setscrews) Inspect the setscrew for wear or damage before installation Follow GRACO equipment manuals for specific installation instructions
