Graco 17W233 Hex Head Cap Screw 1/2-13 x 1.5

Optimize Performance and Reliability with Graco 17W233 Hex Head Screw Cap, 1/2-13 x 1.5

Graco 17W233 Screw, Cap, Hex Head, 1/2-13 x 1.5 stands out as an essential high-performance fastener engineered for demanding fluid handling applications. Precision manufacturing ensures consistent thread engagement and head geometry, making it a trusted element in spray systems, airless sprayers, and industrial fluid connectors. Compatibility across multiple Graco assemblies highlights its versatility, and stringent quality controls guarantee every piece meets rigorous standards for mechanical integrity and sealing performance. Its high yield strength accommodates dynamic pressure cycling above 5000 psi without compromising integrity.

• Precision-machined 1/2-13 threads for secure clamping
• Heat-treated steel for enhanced tensile strength and durability
• Hex head design for reliable torque application and leak prevention

Designed with service technicians and engineers in mind, this screw cap has tight thread tolerances that reduce the risk of cross-threading during assembly or disassembly. An optimized head geometry allows a standard 3/4-inch socket to engage cleanly, minimizing slippage under high torque settings. Smooth chamfers at the base of the head facilitate thin-film gasket installation when used in high-pressure environments, enhancing overall leak resistance and maintenance convenience. Feedback from field service teams highlights reduced assembly errors and faster changeovers.

Metal selection and finishing play a pivotal role in this component’s longevity. Each 17W233 screw is crafted from quenched and tempered alloy steel, achieving a balance between toughness and hardness. Surface treatments include a corrosion-resistant phosphate coating that withstands harsh solvents, paints, and cleaning agents commonly encountered in production yards or on-site finishing operations. This protects against pitting and prolongs service intervals. Complete traceability is supported with batch certificates, facilitating compliance with stringent audit requirements.

Dimensional precision characterizes the aspect ratio and thread pitch of the screw, ensuring less than 0.05 mm deviation over the length of 1.5 inches. Such tolerances are critical when establishing fluid-tight seals in high-volume spray guns or pump manifolds. A uniform hex head height of 0.25 inches maintains socket engagement depth, preserving tool life and operator safety during repetitive installation cycles. Tighter tolerances reduce vibration-induced loosening in high-frequency applications.

Proper installation demands a calibrated torque wrench with a recommended setting of 30–35 foot-pounds, depending on the application’s pressure parameters. When replacing worn or damaged fasteners, technicians should verify mating surface conditions and clean sealing grooves before torque application. Periodic retorque checks after initial run-in can prevent loosening caused by vibration or thermal cycling, ensuring system integrity over extended use. Consistent lubrication of threads prior to assembly reduces wear and inhibits galling under repeated torque cycles.

Compatibility extends across a broad range of Graco systems, from airless paint pods to bulk material pumps. This screw engages seamlessly with both standard and premium seal variants. For those integrating this component into custom machinery or retrofitting existing frameworks, adherence to manufacturer torque guidelines and thread lubrication best practices can optimize operational uptime while avoiding galling. Seamless integration is supported by compatibility charts and torque specification guidance.

Entry-level maintenance personnel and seasoned mechanics alike will appreciate how this component integrates with paint spraying equipment installations, reducing downtime and simplifying preventive service routines. Its robust design streamlines overhauls, and replacement cycles become predictable. Compatibility also extends to retrofitting older series update kits without modification. This fastener aligns with global industry standards for thread form and mechanical performance.

Acquiring this specialized part is straightforward for contractors aiming to minimize supply chain delays. Locating a nearby supplier is simple when searching for graco store near me through authorized dealer networks or digital catalogs. With widespread distribution, technicians can access genuine parts quickly and avoid counterfeit risks that compromise system safety and fluid control accuracy in critical operations. Authorized technicians benefit from structured maintenance schedules provided by Graco-certified training modules.

Extending the lifecycle of fluid delivery components requires a proactive approach and access to authentic service assemblies. Many workshops pair this screw with comprehensive rebuild modules such as Graco Pumps Repair Kits to overhaul pump cradles, gun bodies, and fluid sections. Combining these elements guarantees alignment with OEM specifications and delivers a systematic path to restoring peak performance without guesswork. Investing in authentic components ensures optimal lifecycle management and minimizes unplanned downtime.
