RH320 Induction Heater for Seized Bolts

Name: RH320 Induction Heater
Brand: Autocraft
SKU: RH320

Product Overview

The RH320 is a flameless induction heater that frees rusted-on bolts without an open torch. Induction heat goes into the fastener itself, so a seized bolt can be released in about 30 seconds instead of being cut out. It runs on ordinary workshop single-phase supply and ships with a set of interchangeable coils for different fastener shapes.

Key Benefits

What This Machine Changes in the Bay

Releases a rusted bolt in around 30 seconds, so exhaust, suspension and chassis jobs stop stalling on one seized fastener
No open flame, which removes the fire risk of heating near fuel lines, brake hoses, underseal and wiring
Heat goes into the fastener rather than the surrounding panel, reducing collateral damage the customer would otherwise be charged for
Built-in LED work light keeps the joint visible while the coil is working
Multiple coil shapes cover nuts, studs, bearings and body fasteners with one tool

Application Scenarios

Exhaust and catalytic converter replacement on salted-road vehicles
Suspension and subframe bolts that have corroded into place
Bearing and bushing removal where a torch cannot be used safely
Farm equipment, marine and general machinery repair away from a fabrication bay

Who It Is For

Independent repair workshops handling older vehicles and rust-belt bodies
Exhaust and suspension specialists who lose labour hours on seized fasteners
Mobile mechanics who cannot carry oxy-acetylene equipment
Fleet and agricultural machinery workshops

Problems It Solves

What It Stops Costing You

Cutting and re-threading seized bolts turns a 20-minute job into a half-day repair
Torch work near fuel, brake and electrical lines forces the vehicle onto a dedicated bay
Heat spread from a flame damages paint, underseal and nearby components
Broken extractor bits and drilled-out studs create warranty arguments with the customer

Compared With Other Models

Against an oxy-acetylene torch: no gas bottles, no open flame and no exclusion zone around fuel and brake lines
Against penetrating fluid alone: works on fasteners that have corroded solid rather than merely tightened
Against drilling and re-tapping: the original thread is usually recoverable, so no helicoil repair is billed

Use Guide

Select the coil that matches the fastener shape and lock it with the rotary lock
Place the coil around the nut or stud without touching surrounding paintwork
Apply heat in short bursts and watch the joint under the LED light
Back the fastener off while it is still hot, then let the coil cool before the next cycle

RH320 Questions Buyers Ask

What power supply does the RH320 need?

It runs on 220V/110V at 50/60Hz, so it works on standard single-phase workshop supply in most markets. Confirm the voltage variant you need when ordering.

How long does it take to free a seized bolt?

A rusted bolt can typically be released in about 30 seconds. Badly corroded or oversized fasteners may need a second heating cycle.

Is it safe to use near fuel and brake lines?

There is no open flame, which is the main reason workshops move to induction. Normal workshop precautions still apply: keep the coil clear of plastic lines and wiring.

Which coils are included?

The tool is supplied with a set of coils covering different fastener types. Tell us the jobs you do most and we will confirm the coil set on the quotation.

What is the minimum order quantity?

Single units are available for workshops, and we quote carton and pallet pricing for distributors. Send us your target quantity for a landed price.

How is it packed for export?

The heater and coil set ship in a carton sized for air or sea freight. We confirm carton dimensions and gross weight before booking.
