Ordering Information 3.2.11.1 Product Description X-BT-ER stainless steel threaded studs are designed for electrical connections under permanent current, short circuit current and lightning current conditions. Packaged with two stainless nuts and one stainless steel lock washer, the X-BT-ER can be used for electrical grounding such as bonding and lightning protection under corrosive environments. The X-BT-ER is available in W6/7 SN4 and W10/3 SN4 sizes. Product Features and Benefits Fast: A connection can be made in less than 1 minute. Removing and reapplication of coatings are not required. Reliable: Stainless steel stud is generally suitable for corrosive industrial environments. The vibration resistant stud prevents the connection from accidentally coming loose. Simple: Drill, fasten and connect. External power source is not needed and not dependent on weather.
