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. :contentReference[oaicite:4]{index=4}
• 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). :contentReference[oaicite:5]{index=5}
• 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. :contentReference[oaicite:6]{index=6}

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. :contentReference[oaicite:7]{index=7}
• Standard size (M5 × 10 mm): suitable for the mounting points specified by Graco — ensures proper fit and compatibility without need for modification. :contentReference[oaicite:8]{index=8}
• OEM‑specified part: using original part helps maintain manufacturer’s safety design; generic substitutes may not guarantee the same electrical continuity or mechanical fit. :contentReference[oaicite:9]{index=9}
• 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. :contentReference[oaicite:10]{index=10}

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.
