Frequently Asked Questions
What tools do I need for basic car maintenance or repairs?
Basic automotive work typically requires sockets, spanners, screwdrivers, pliers, and specialty tools such as bolt extractors. A bolt extractor set is especially useful when dealing with damaged, rusted, or rounded fasteners that cannot be removed with normal sockets.
Difference between a socket and a spanner?
A socket is designed to fit onto a ratchet or breaker bar and surrounds the fastener for improved grip and torque. A spanner grips the sides of the fastener from the outside. Sockets generally provide better leverage and are commonly used in automotive and mechanical work.
Why do bolts strip easily?
Bolts can strip due to incorrect tool sizes, excessive force, corrosion, or worn fastener heads. Using proper tools like spiral bolt extractors helps remove stripped bolts without damaging surrounding components.
How do I stop bolts from loosening?
You can prevent bolts from loosening by tightening them to the correct torque specification, using thread-locking compounds, lock washers, or nyloc nuts. Regular inspection and maintenance also help prevent fastener failure.
