Abstract
An improved fastener includes a fastener body and a blocker. The fastener body has an end functioning as a connecting head, and center of the fastener body forms an axial threaded bore. An end of the axial threaded bore corresponding to the connecting head is formed into a recess surrounded by the connecting head. The blocker is removably fitted in the recess of the fastener body. When the connecting head of the fastener body is extended through a fixing hole on a printed circuit board with the blocker fitted in the recess, solder paste applied over the fixing hole is prevented from entering into the axial threaded bore of the fastener body to interfere with a screw being threaded into the fastener body.
