$6.55The Graco 114528 Pan Head Machined Phillips Screw is engineered to deliver critical fastening integrity in demanding fluid spray assemblies. Designed as an OEM replacement for original Graco parts, this screw integrates perfectly with high-pressure pump housings and manifold connections. Its precision-machined profile ensures consistent head seating and torque distribution, enhancing overall airless sprayer structural stability. Ideal for professional maintenance crews and equipment manufacturers, the 114528 model supports robust hydraulic sealing and vibration resistance under extreme operating conditions.
At the core of the part’s performance is a pan head geometry that optimizes clamping force distribution across mating surfaces. With a thread form matching Graco’s stringent specifications, the 114528 screw resists back-out under cyclic pressure loads. Its surface finish rating of 16 µin Ra minimizes friction and protects sealant adhesions at high hydraulic pressures. Applications extend from spray pump inlet filters to fluid path valves, ensuring uninterrupted operation in professional coatings environments.
Constructed from high-carbon alloy steel, each screw undergoes a multi-stage heat treatment to achieve a Rockwell C hardness of 30–35. A proprietary nickel-chrome plating provides 1,000+ hours of salt spray resistance, preventing corrosion in corrosive jobsite atmospheres. This plating also preserves thread integrity during repeated service interventions. The result is a fastener capable of maintaining precise torque levels over extended service cycles, directly contributing to improved professional coatings consistency and reduced downtime.
The pan head profile with a shallow crown height maximizes bearing surface area, reducing embedding into soft housings. The Phillips drive sizing meets ANSI B18.6.3 standards, ensuring compatibility with common torque drivers and impact tools while controlling cam-out. Thread pitch and root radius follow ISO 261:1998, offering smooth engagement with tapped pump housings and manifold blocks. Engineers routinely specify this part when balancing installation speed against long-term joint integrity in precision fluid control modules.
In advanced spray equipment such as the Graco GMAX II 5900 HD ProContractor system, the 114528 screw secures critical filter assemblies that support high-pressure filtration processes. Its reliable clamping force helps maintain constant fluid flow rates and prevents micro-leakage that can compromise spray pattern consistency. The screw’s dimensional stability at temperatures up to 120 °C makes it suitable for thermal cycling in ambient or heated fluid circuits. Integrators value the part for its adaptability across manifold blocks, pump bodies, and valve seats in heavy-duty spray packages.
Torque-to-yield benchmarks for the Graco 114528 typically average 15 in-lb (1.7 N·m) for aluminum housings and 20 in-lb (2.3 N·m) for steel assemblies, delivering predictable clamp loads without material deformation. The part’s shear strength exceeds 1,200 N, ensuring joint security under dynamic vibration and pressure pulsations. Long-term sealing performance is reinforced by consistent preload retention, directly improving seal longevity in critical O-ring and gasket interfaces.
For optimal results, apply a light thread lubricant rated for hydraulic applications and torque screws in a star pattern on multi-bolt flanges. Use a calibrated torque driver to prevent over-tightening and avoid damage to housing threads. Periodic inspection during routine servicing allows for quick verification of torque integrity, supporting preventive maintenance regimes in professional spray operations. Replacement intervals align with major pump rebuilds and filter changes, typically every 6–12 months under continuous operation.
By integrating the Graco 114528 Pan Head Machined Phillips Screw into high-pressure spray systems, engineers and service technicians can achieve superior joint consistency and long-term reliability. Its precision manufacturing, robust material properties, and compatibility with key spray components make it a cornerstone in professional fluid delivery solutions, from heavy-duty contractor sprayers to specialized industrial coating lines.
