$6.3The Graco 113160 machine-screw assembly combines a slotted hexagonal head with an integrated washer profile to deliver consistent clamping force in demanding fluid delivery systems. Engineered for compatibility with Graco pump modules and manifold interfaces, this part is fabricated to exacting tolerances to ensure reliable torque transfer and leak-free sealing in high-pressure environments. Manufactured from a hardened stainless steel alloy, it exhibits superior resistance to abrasion and chemical attack, making it a vital element for industrial airless sprayer and professional spray equipment. As such, it is especially valuable in texture paint sprayer modules where robust mechanical retention is essential under vibration. Its compact geometry supports ergonomic tool access while preserving structural integrity in confined pump housings.
The 113160’s hexagonal slotted head undergoes CNC machining to achieve surface finishes below 0.8 μm Ra, enabling precise torque application during installation. Integrated washer-head geometry distributes clamping loads uniformly across composite or metallic manifolds to reduce stress concentrations and micro-leak pathways. Each fastener is subject to ultrasonic cleaning and passivation to uphold optimal high-pressure filtration standards in fluid passages. This rigorous manufacturing approach enhances pump efficiency and ensures compatibility with professional coatings systems, minimizing particulate shedding into sensitive valve assemblies. When used in combination with original Graco pump kits such as the graco airless paint sprayer ProSeries lines, this screw contributes to sustained operational integrity over extended duty cycles.
Operational testing of the Graco 113160 reveals superior resistance to galling and torque relaxation under cyclic loading, supporting applications in heavy-duty sprayer modules. The integrated washer head facilitates enhanced seal longevity by maintaining uniform flange compression across PTFE or elastomeric gasket materials, directly impacting leakage rates and service intervals. In systems employing high-pressure filtration for abrasive or particulate-laden coatings, the screw’s tight pitch thread profile helps preserve contiguous fluid pathways, preventing bypass and ensuring consistent flow rates. Its corrosion-resistant plating offers protection in salt-laden or solvent-rich atmospheres, preserving the fastener’s dimensional stability. The part’s traceable lot coding supports batch-level quality control for corrective action analysis and preventative maintenance scheduling. Periodic inspection protocols recommend verifying torque retention and checking for microabrasion at the head-to-shank transition, especially in extended runtime scenarios within sprayer machine paint circuits.
Proper installation of the Graco 113160 requires adherence to specified torque values, typically 40–45 in-lb for stainless steel manifolds and 35–40 in-lb when engaging composite housings to prevent thread stripping. A properly sized hex driver or socket with a thin-wall profile enables precise engagement of the slotted head, reducing the risk of slippage during assembly. To optimize pump efficiency and minimize assembly downtime, technicians should apply a compatible anaerobic sealant or anti-seize compound in accordance with system fluid compatibility guidelines. This screw is widely adopted in OEM and aftermarket pump rebuild kits where durable fastening hardware is essential for maintaining pressure ratings above 3000 psi. Calibration of torque tools and periodic retightening checks are recommended after the first 1000 operational cycles to sustain preload integrity.
The Graco 113160 screw assembly adheres to stringent ISO 9001:2015 quality management system standards, with each production batch undergoing non-destructive evaluation and dimensional verification using coordinate measuring machines (CMM). Certified material grades meet ASTM A479 requirements for corrosion-resistant alloys, delivering a minimum tensile strength of 550 MPa and shear strength exceeding 400 MPa. A controlled plating process applies a 5–8 μm zinc-nickel layer to enhance chemical stability in solvent-rich environments and maintain surface conductivity within electrical grounding applications. Batch-level marking on each fastener enables full traceability for corrective action analysis and preventative maintenance scheduling. Final inspection includes torque testing at 105% of nominal setpoint and sealability assessment under a 5000 psi hydrostatic test, confirming leak integrity and compliance with industrial airless sprayer operational benchmarks.
In summary, the Graco 113160 hexagonal head machined washer/screw represents a cornerstone fastener for demanding airless spraying platforms. Its blend of precise CNC-finished geometry, heat-treated material composition, and corrosion-resistant finishing ensures robust performance in professional coatings and fluid delivery systems. Designed to integrate seamlessly with Graco pump and valve assemblies, it contributes to reduced downtime and consistent spray patterns under the most challenging operational conditions. Maintenance teams will appreciate the part’s traceable manufacturing data and straightforward installation process, aligning with stringent quality management protocols in industrial coating facilities.
