Comprehensive Details on the Graco 15B564 Socket Low‑Head Cap Screw

Compatible Assemblies & Usage

The Graco 15B564 Socket Low‑Head Cap Screw is used throughout various Graco systems where low-profile, high-strength fasteners are required. Most commonly, it secures guard assemblies, mounts motor brackets, and is part of internal structural components in Graco pump and spray units.

Product Description

This is a precision machined, recessed-socket cap screw designed specifically for demanding industrial applications within Graco’s fluid‑handling and spraying systems. Its low head design makes it ideal for use in tight spaces where flush mounting or minimal protrusion is critical.

Built from a high-grade alloy, the screw offers excellent tensile strength and resistance to vibration-induced loosening, ensuring that assemblies remain secure even under high-pressure or high-cycle conditions.

Key Features

Importance in Your System

Using the correct fasteners in high-precision equipment like Graco sprayers is critical: an incorrect or undersized screw can loosen, strip, or fail under load. The 15B564 provides secure fastening with minimal head height, reducing snag points and allowing compact assemblies to remain streamlined.

When & How to Replace

• Check for thread damage, corrosion, or signs of stripping during routine maintenance.
• Replace any screw that shows deformation or wear to preserve assembly integrity.
• Use the correct torque as per Graco’s specifications to avoid over-tightening or damaging the thread.
• If reusing, apply a thread-locking compound or anti-vibration treatment if the system experiences frequent vibration.
