1. 表中LG為最大值,表示螺釘的最小設計夾緊長度。測量時将一個無螺紋内倒角或無沉孔的通端螺紋環規,用手盡力擰入螺紋,直到擰不動為止,此時測得的從頭部支承面到螺紋環規端面之間的距離即為LG。表中LB為最小值,表達的是螺釘的最小無螺紋杆部長度。對于每一個長度規格,無螺紋杆部長度等于LG減去5倍的螺紋螺距(UNRC系列)。 2. 對于公稱長度位于表左側兩檔公稱長度之間的規格,其LG、LB按表中相鄰公稱長度中較短一檔的LG和LB。例如:公稱直徑1/4 in,公稱長度1.88 in的螺釘,LG為0.50 in,LB為0.25 in。 3. 表中“-”公稱長度的螺釘,為全螺紋(滿扣)產品。檢查時用一個無螺紋内倒角或無沉孔的通端螺紋環規,用手盡力擰入螺紋。對于公稱直徑從0#(0.0060 in)至5/8 in(包括5/8 in)的螺釘,其螺紋肩距最大不超過2倍螺距;對于公稱直徑大于1 in和長度小于最小螺紋長度LT加5倍螺距(UNRC系列)的螺釘,應為全螺紋(滿扣)產品。其肩距可根據實際情況,但也應盡可能小。 4. 對于公稱長度大于本表中,已規定LG和LB值所對應長度尺寸的螺釘和公稱直徑大于1 in的螺釘,其最大夾緊長度LG和最小無螺紋杆長LB,見表2。 LG=L-LT LB-L-LTT |
