Graco 116343 Grounding Screw M5 x 10mm

Graco 116343 Grounding Screw (M5 × 10 mm)

The Graco 116343 Grounding Screw is a small but critical OEM-specified grounding fastener used in compatible Graco pumps, sprayers, and fluid-handling equipment. Its purpose is to securely connect the equipment’s metal housing or chassis to earth ground — reducing the risk of static build-up, electrical faults, or electrostatic discharge during operation.

Compatible Equipment / Applications

• Graco pumps and spray systems that list part # 116343 as the grounding screw in their parts breakdown.
• Spray-painting or coating rigs, proportioners, fluid-handling systems where grounding is required for safety or to prevent static-related hazards (especially in high voltage / electrostatic guns).
• Any maintenance, repair or rebuild job of Graco equipment where the original grounding screw is lost, damaged or corroded — replacing with 116343 restores correct grounding path.

Key Features & Safety Role

• Grounding / Earthing function: ensures the equipment’s metal body or fluid-path components are electrically grounded — important for safety and to avoid static discharge or shock.
• Standard size (M5 × 10 mm): suitable for the mounting points specified by Graco — ensures proper fit and compatibility without need for modification.
• OEM-specified part: using original part helps maintain manufacturer’s safety design; generic substitutes may not guarantee the same electrical continuity or mechanical fit.
• Important for electrostatic / high-pressure spray systems: proper grounding ensures safe operation, reduces risk of static charges, and may improve spray/paint transfer efficiency in electrostatic setups.

When & Why to Use / Replace

• Install or replace when original grounding screw is missing, damaged, loose or corroded — to restore safe grounding and avoid electrical hazards.
• Always check grounding screw during maintenance, especially before using spray/paint/coating equipment — proper earthing is crucial for safety.
• Use OEM grounding screw (116343) rather than generic screw to ensure proper thread, size, and reliable earth-connection.
