*Be safe. Position yourself such that if your hand slips, you're not going to hurt yourself. It is usually safer to push away from yourself (if you slip while pulling, a wrench to the face/ribs does not feel good). Best practice is to fit yourself with appropriate mechanic's gloves in the event you slip or the fastener abruptly moves, hands can impact adjacent objects. | *Be safe.

Penetrating oil is an extremely low-viscosity oil that can penetrate into the area between threads on fasteners. A stuck fastener is sometimes repeatedly heated, sprayed with penetrating oil, and then tapped with a hammer. | Penetrating oil is an extremely low-viscosity oil that can penetrate into the area between threads on fasteners.
