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.

Additional Options:
Typical sizes for electric bolt heaters include: .250”, .375”, .438”, .500”, .550”, .688”, .781”, .813”, .938”, 1”, and 1.250”. If you do not see the size you need here, contact us and we will make it for you.
