Abstract

892,442. Socket-head screws. UNBRAKO SCHRAUBEN G.m.b.H. Sept. 28, 1960, No. 33241/60. Class 89(1). A screw with a cylindrical head, having knurling 14 for enabling the screw to be fingerdriven into a recess 13 to a certain position as indicated, has a knurled annular portion (which may be on a chamfer 15 as shown, or on an annular portion in the plane of the head end or on both) to enable it, with axial pressure, to be finger-driven further. Fig. 4 (not shown), so that less use of a key in a socket 11 is required, for final tightening.
