3.2.15.6.1 Product description
S-BT-ER stainless steel screw-in threaded studs and S-BT-EF carbon steel screw-in threaded studs are designed for electrical connections under permanent current , short circuit current , and lightning current conditions . Packaged with two stainless steel nuts and one stainless steel lock washer , the S-BT-ER can be used for electrical grounding such as bonding and lightning protection under corrosive environments . The S-BT-EF is packaged with two carbon steel nuts and one carbon steel lock washer to be used in noncorrosive environments . High current versions of the S-BT-ER and S-BT-EF are also available ( S-BT-ER HC and S-BT-EF HC ), which are packaged with one nut , one lock washer , and one copper alloy conductivity disc .
Product Features and benefits
• No propellants required .
• No through penetration of steel base materials 1 / 4 " and thicker .
• Little to no rework of coated steel required for non-through hole applications with base material thickness larger than 1 / 4 ''.
• Offer fastening options for both stainless and carbon steel materials .
• Easier removal — S-BT fastener is removable .
