TopHat® Screw-On Classic Pin Points feature a time tested design cast in black burnished steel. These sturdy steel points will stand up to lots of shots. The arrow point is threaded onto the blunt shaft (no glue or taper required). The thread inside the arrow point attaches firmly to the shaft, making accidental loosening impossible. Available in 5/16" - 70 grains, and 11/32" - 80 and 100 grains. Please specify. Sold by the 6 pack. Please note: It is recommended that you buy the TopHat® Thread Cutting Tool, TopHat® Shaft Shaper, and TopHat® Assembly Tool to use with these points. The TopHat® Thread Cutting Tool is for starting a thread onto the shaft to make it easier to install Screw-On points. The TopHat® Shaft Shaper is for compressing down an oversized shaft so the finish will not be marred when installing points, and to allow the points to go on easier. The TopHat® Assembly Tool is for gripping the point, the Thread Cutting Tool and The Shaft Shaper without marring them for easy tightening and removal of TopHat® points.
