The Graco 15H318 Screw SHCS M4 × 0.7 is a precision socket‑head cap screw with M4 × 0.7 thread size, built for exact application in Graco equipment sub‑assemblies.
The 15H318 Screw SHCS M4 × 0.7 is a calibrated socket‑head cap screw with thread size M4 and pitch 0.7 mm, constructed for use in Graco equipment sub‑assemblies that require a compact, strong fastener with precise dimensions. This screw supports component alignment, ensures correct clamping, and helps maintain assembly integrity in professional spray and coating systems.
