Blackburn 50030SW-C – Frequently Asked Questions
1) What bolt size does the Blackburn 50030SW-C split lock washer fit?
The 50030SW-C is sized for 1/2 inch hardware, so it seats under the nut or bolt head on a 1/2 inch bolt or stud. Pick the washer size off the bolt diameter, not the wrench size.
2) Is a silicon bronze lock washer required for bronze grounding connectors, or can I use steel?
Use bronze with bronze. The 50030SW-C is silicon bronze, which matches the material of bronze grounding lugs and connectors and avoids the dissimilar-metal galvanic corrosion you get when a plated steel washer sits against a bronze or copper connection in a ground system or an outdoor pit.
3) What does a split lock washer do that a flat washer won't?
A split (helical spring) washer is cut and sprung open, so when the nut is drawn down the washer compresses and keeps tension on the joint, resisting loosening from vibration. A flat washer only spreads the load over a wider bearing area. On grounding and bonding hardware that sees thermal cycling or vibration, the split type is what holds the connection tight. The 50030SW-C is the split type.
4) Can I use this bronze washer on a direct-buried or outdoor ground rod connection?
Silicon bronze is the standard material for buried and exposed grounding hardware because it resists corrosion in soil and weather, and the 50030SW-C is silicon bronze throughout rather than plated. Match it to a bronze connector and bronze bolt for a uniform-metal joint.
5) Where is the Blackburn 50030SW-C bronze lock washer made?
Country of origin runs across Taiwan, Japan, South Korea, Switzerland and Italy depending on the production lot. If a submittal or a Buy America style requirement pins you to one origin, treat that as a lot-level check rather than a single fixed answer.
6) What part number should I put on the order for a 1/2 inch bronze split lock washer from Blackburn?
Order Blackburn 50030SW-C. That is the manufacturer part number for the silicon bronze split lock washer sized to 1/2 inch hardware, and it is the only model on the item.
