Facom 1/2" Drive 12pt Fractional Socket Set (S.40U) - 7pc box set packaged with a storage rail. OGV design....applies torque through the flats of the fastener. Includes shallow depth sizes...3/8", 7/16", 1/2", 9/16", 19/32", 5/8" and 21/32". Sister set S.41U picks up the larger sizes from 11/16" to 1". Sizes above 1" (ie, 1 1/16, 1 1/8, 1 3/16, and 1 1/4") are sold separately as open stock items)
The FACOM S.40U is a professional-grade 1/2" square drive SAE fractional socket set serving as the smaller-size sister collection to the S.41U. Engineered for shallow clearances, these fractional sockets feature FACOM's proprietary OGV® 12-point torque profile. The OGV profile shifts contact away from the easily damaged corners of a hex nut and onto its flat side walls, resulting in a significantly more powerful tightening grip and lower tool wear.
