35 Pcs Spiral Screw Extractor Bolt Extractor Set - Multi-Size Repair

In this review of the 35 Pcs Spiral Screw Extractor Bolt Extractor Set, the reviewer finds a versatile kit aimed at DIYers and mechanics who need a single set to tackle broken or stripped fasteners. The bottom line: this kit shines for routine removal tasks because it combines multiple extractor styles and left-hand drill bits in a single, solid storage case, making it easy to pick the right tool quickly. The review highlights practical performance, durability claims, and the one notable caution about using the cobalt bits on stainless steel.

Key Features

• Multi-size set: The 35-piece assortment includes multi-spline extractors, spiral screw extractors, left-hand cobalt drill bits, nut removers and an extension, so a single kit covers most stripped fastener scenarios.
• High hardness materials: Made from Cr-Mo steel and 4341/6542 HSS materials, the components are designed to resist wear and offer long service life under normal workshop use.
• Spiral pattern grip: The spiral extractors provide strong biting action that helps the tool grab rounded or damaged fastener heads for faster removal.
• Practical drill bits: The left-hand cobalt drill bits let you drill into the damaged fastener and often back it out without a separate set of drills, though they are not recommended for stainless steel.
• Organized storage: The hard plastic case keeps all 35 parts organized and portable, which makes it simple to carry the kit to job sites or tuck into a toolbox.

Who It's For

This kit is best for homeowners, hobby mechanics and light to medium tradespeople who encounter broken or stripped screws, bolts and nuts and want a single, compact kit to handle a wide range of sizes. The variety of extractor heads and the inclusion of a driver extension make it useful for common workshop and garage jobs where fast access to different extractor types matters.

Those who frequently work on stainless steel fasteners, or who need industrial heavy-duty extraction under extreme torque, should look elsewhere or pair this set with hardened, stainless-rated drill bits, since the cobalt left-hand bits are explicitly not intended for stainless steel use.

Pros & Cons

Pros

• Comprehensive 35-piece set covers most extraction needs without buying separate tools.
• Durable materials like Cr-Mo and HSS increase resistance to wear in everyday use.
• Case and extension improve portability and access to confined fasteners.
• Spiral and multi-spline extractors give options for both rounded and partly exposed fasteners.

Cons

• Cobalt left-hand drill bits should not be used on stainless steel, limiting their use in some repairs.
• Some users reported occasional breakage of bits under heavy stress, so extreme torque applications may exceed the kit's limits.

Our Verdict
