FIELD: machine building.

SUBSTANCE: installation tool for automatic assembly of threaded connections consists of a shank end and of a working part with a shaped seat with internal components of engagement in form of alternating lugs and recesses. The shaped seat has double lead-in face with angle α=60÷62° on length ℓ=1.1÷1.3h, where H is height of the face on a face head of the fastener and additionally within this face range a conic section with angle β=2÷4° is made on length ℓ₁=h along internal components of engagement.
