Graco 15B588 Socket Head Cap Screw

Comprehensive Overview of the Graco 15B588 Socket Head Cap Screw

Intended Applications

The Graco 15B588 Socket Head Cap Screw is a purpose‑built high‑precision fastener used in various Graco equipment assemblies where secure, flush mounting is required — particularly in gear housings, pump frames, motor mounts and other structural assemblies.

Product Description

This screw features a cylindrical head with a recessed hex socket drive, enabling a clean and compact installation profile. The design allows for tight, reliable fastening in confined spaces, minimizing protrusion and interference with surrounding components.

Manufactured to OEM standard by Graco, the 15B588 cap screw uses a high‑tensile alloy and precision thread cutting to ensure consistent fit, resistance to vibration loosening, and long service life. It plays a critical role in maintaining structural integrity within high‑performance spraying and fluid handling systems.

Key Features & Specifications

Why This Fastener Matters

In high‑duty industrial equipment from Graco, the integrity of mechanical loads — connection strength, torque retention, alignment — all rely on properly fitted fasteners. Using a generic or undersized screw may result in loosening, fatigue, or misalignment under vibration or pressure. The 15B588 cap screw ensures the correct fit, material strength and design match to preserve assembly reliability and performance.

Installation & Maintenance Guidance

• Ensure clean threads and proper mating surfaces before installation.
• Apply the correct torque value specified by the equipment manual to avoid over‑stress or under‑tightening.
• Check for signs of thread stripping, head deformation, or corrosion during scheduled maintenance.
• If equipment exhibits vibration or loosening at screw joints, replace the fastener with the OEM 15B588 to restore original performance.
