FIELD: machine engineering, possibly automatic assembling of threaded joints. SUBSTANCE: flanged bolt with shaped head includes threaded rod, flange with supporting surface and shaped head with outer engaging members for mounting tool. Said members are in the form of alternating longitudinal dents and recesses joined along radiuses. Supporting surface of flange is in the form of disc with angle γ no less than 0 degrees 20' and no more than 2 degrees. Height h of flange is determined by relation 
where dr is diameter of bolt rod on loaded portion with least cross section; Dh is outer diameter of bolt head along dents, Df is diameter of flange, γ is inclination angle of supporting surface, dn is diameter of bolt neck. Flanged bolt with locking properties has small mass, high strength in axial direction. EFFECT: enhanced stability of joint with such bolt. 1 dwg
