Item # LHHSCS03750XXX, Low Head Hexagon Socket Cap Screw, 0.3750" Nominal Dia. On Sales Systems Ltd.

General Note: This product, although a high strength precision fastener, is recommended for lighter fastening applications. It is not suggested for use in critical high strength applications where socket head cap screws should normally be used. They are designed to be used in applications where head height clearance is a problem. Because of their reduced head height, and smaller socket size, they normally cannot be properly preloaded as a standard socket cap screw and should not be subjected to high dynamic loads.

Nominal Size. Where specifying nominal size in decimals, zeros preceding decimal and in the fourth decimal place shall be omitted.
Body. The term body refers to the unthreaded cylindrical portion of the shank for those screws not threaded to the head.
Head Diameter. Heads shall be plain, not knurled.
Head Chamfer. The top of the head shall be flat. The intersection of the top of the head and side of the head may be chamfered or radiused within the limits of C, at the manufacturer's option.
Bearing Surface. The plane of the bearing surface shall be perpendicular to the axis of the shank, with a maximum deviation of one degree, obtained by holding the screw on the body or major thread diameter within one dia. of the bearing surface of the head, but beyond the maximum
