The 5/16" drawn steel points are measured in outside diameter, and require no taper, but require a parallel tenon (see illustration) to slide inside the point. Then simply glue or crimp on. For the 1/4" drawn steel points no taper or tenon is required. They are ready to glue or crimp on. Approximately 20 grains each.
Choose Outside Diameter of 1/4" or 5/16". Sold by the dozen and 100 count. Please specify.
