Martin BC8K SAE Wrench Set, 8 Pieces, Polished Chrome

Crowfoot socket wrench attachments are drop forged from steel bar. These wrenches are available in drive sizes of 3/8 in and 1/2 in, in 12 point flare-nut openings in fractional sizes. They come in chrome and industrial black finish. These are special purpose attachment heads designed to accept either a socket wrench handle or extension piece, for use in tightening or loosening nuts which are in odd positions. The 12 point flare nut design provides extreme flexibility in addressing these situations. The extra head thickness provides maximum surface contact area and helps prevent marring of fittings.
