Uses:
Used to preheat large, hollow holding bolts or studs where a high concentration of heat is critical for bolt expansion in a short time. Manufactured with a high watt density, they heat up in just a few minutes, resulting in cost savings on reduced man hours removing nuts from bolts and studs. Large bolts can be heated to full expansion in just a few minutes.

Specifications:
The hole diameter should be as close to heater diameter as possible, but within approximately 1/16” (.062) clearance for insertion applications. Close tolerance permits maximum heat transfer and prolonged heater life. Bolt Heaters come without plugs, but plugs can be added if requested

Additional Options:
Sizes for electric bolt heaters include: .250”, .313", .375”, .394, .438”, .472", .500”, .512", .531", .550”, .625", .669", .688”, .750", .787”, .938”, .984", 1”, and 1.250”.

Note: We keep a few sizes of electric bolt heaters in stock, but most of them are made to order. If you need a Bolt Heater right away, consider a Gas Bolt Heater. They can't be used in every application, but the sizing is more universal and they are always in stock.

Extension cords (of any length) are available upon request.
