Question 2

What are the key specifications and materials for this socket?

Accepted Answer

Size: 13/16". Drive: 3/8". Construction: chrome vanadium steel, heat treated. Finish: chrome plated for corrosion resistance. Features: magnetic interior, large size markings for quick identification, off-corner loading design, and a single-hex (6-point) fastener end.

Question 3

Off-corner loading shifts the contact area away from the corners of the fastener, which helps reduce rounding and wear on the spark plug and surrounding head, extending tool life and protecting your fasteners.
