Abstract

Patente de Invenção: "PARAFUSO DE AUTO-ROSQUEAMENTO". Parafuso de auto-rosqueamento com voltas de rosca enroladas nas quais o bissetor do ângulo da volta da rosca formado pelo flanco da carga e o flanco traseiro se inclina para longe da cabeça do parafuso em um ângulo para a perpendicular do eixo do parafuso, o flanco da carga atua em uma linha reta até a raiz da rosca e o flanco traseiro se estende inicialmente em uma linha reta a partir da extremidade da rosca e a cerca de 113 de sua altura, se introduz, via uma torcedura, em uma parte do ângulo que é superior ao ângulo medido em relação à perpendicular do flanco traseiro é entre 300 e 500, a proporção do diâmetro do núcleo da rosca para o diâmetro externo da rosca sendo superior a 0,7 e a proporção da etapa da rosca para o diâmetro externo da rosca sendo inferior a 0,25.
