The Beta Tools T-handle Spark Plug Wrench, No. 959, allows the technician to safely thread the spark plug without over-tightening or cross-threading. Compared to a ratchet, the 959 installs the spark plug with much more precision and control helping to avoid the threat of cross-threading, according to the company. The T-handle acts as a breaker bar for easy removal of spark plugs and with approximately 20" of length, it provides easy access. The 959 comes in 9/16”, 5/8” and 13/16” socket sizes.
