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”.
