ESCO 30100 Save-A-Stud FAQ
What thread sizes does the 30100 kit cover?
The 7-piece ESCO 30100 kit includes dies for 7/16", 1/2" SAE Left, 1/2", 9/16", 5/8", 12mm-1.25, and 12mm-1.5 thread pitches. These cover most common passenger vehicles including disc brake systems, four-wheel drive, and front-wheel drive platforms. For heavy-duty trucks, see the 30120 nine-piece kit with additional sizes.
Can I use this kit on any vehicle?
The 30100 is designed for passenger vehicles with the thread sizes listed. Heavy-duty trucks, light-duty trucks (depending on year/model), and European imports with 12mm studs are all compatible. The 30120 heavy-duty variant covers larger truck studs. Always verify the stud thread size and pitch before selecting the correct kit.
Do I need to remove the caliper, rotor, or stud to use this tool?
No. The Save-A-Stud is specifically designed to renew threads without removing the caliper, rotor, or existing damaged stud. This is the primary advantage over traditional stud replacement. The tool threads new material directly over the damaged area, restoring the threads in approximately 30 seconds.
What is the repair time per stud?
Most studs are repaired in approximately 30 seconds using the patented hinged die design. Total job time depends on number of damaged studs per wheel and access conditions, but this tool reduces labor dramatically compared to rotor removal and stud replacement.
How durable are the dies?
ESCO dies are manufactured from hardened tool steel and backed by a lifetime limited warranty. The patented hinged design provides superior durability compared to split-die tools. Proper storage in the included carrying case and normal use ensure years of reliable performance. Dies do not need replacement under warranty unless defective.
Is the carrying case included?
Yes. The ESCO 30100 kit comes complete with a plastic carrying case (12" x 6" x 6") that holds all seven dies. The case protects the dies and makes the kit portable for shop use, mobile service vehicles, or job site transport.
What warranty does ESCO provide?
ESCO provides a lifetime limited warranty covering defects in materials and workmanship for the first purchasing end-user. The warranty begins on the date of shipment and is non-transferable. Normal wear and tear, misuse, and improper storage are excluded. Defective products are repaired or replaced at ESCO's discretion.
Can individual thread size dies be purchased separately?
Yes. ESCO offers individual dies for each thread size included in the 30100 kit. This allows shops to replace worn dies, expand kit capability, or stock commonly used sizes. Contact an ESCO distributor for individual die pricing and availability.
Who manufactures the ESCO Save-A-Stud?
ESCO Equipment is the global leader in tire service equipment with over 50 years of industry experience. Based in the United States, ESCO serves automotive, agricultural, commercial, mining, and off-road markets. The company is trusted by dealerships, tire shops, fleets, and mobile service technicians worldwide for innovative, reliable tools.
How does this compare to traditional stud replacement?
Traditional stud replacement requires removing the caliper, rotor, and brake system components - often a one-hour job. If the rotor warps during service, both rotors must be turned or replaced. The Save-A-Stud eliminates these steps, renewing threads in 30 seconds without disassembly. This saves labor costs and reduces rotor replacement expenses.
Is this tool suitable for fleet and mobile service applications?
Yes. The lightweight (1 lb) and compact design (12" x 6" x 6") make the 30100 ideal for mobile service technicians, fleet service centers, and multi-location chains. Fast repairs reduce vehicle downtime and improve shop productivity.
What is the return policy?
Returns are accepted within 30 days of delivery for unopened products in original packaging with receipt. A 20% restocking fee applies to non-defective returns. Buyer is responsible for return shipping costs. Defective products are replaced at no cost within the warranty period without restocking fees.
