Description:
<br/><b>CRL Self-Tapping Machine Screws</b> are used to mount clips to steel casement windows. They have special cross-cuts which allow them to tap their own threads in metal. They attach thin materials to substrates with pre-drilled holes, as with storm and screen window clips being attached to aluminum window frames. <br/> Quantities of 100 are packed in plastic re-sealable tubs, and bulk packages of 1,000 are packaged in poly bags. Both feature easy-to-read labels in see through packaging.<br/><p>Most shipping weights are approximate and have not been verified.
