The standard and universal 8/32 arrow thread size perfectly fits the standard size shafts 5mm, 6mm, & 6.5mm with inserts using an 8-32 thread pattern. While Deep Six fits small diameter 4mm shafts with inserts that use the Deep Six thread pattern. Deep Six is the broadhead thread standard and a mini-sized insert that started the production of a smaller broadhead-compatible and ultra-micro diameter arrow shaft. When Ultra-Micro Easton Arrows emerged in the market, it created a pivotal change in equipment designed and designated for serious bowhunting. With more options for penetration, hunters consider Deep Six thread broadheads, arrows, and inserts worthy in the archery field. For hunters, Deep Six tipped arrows provide them more penetration by concentrating the arrow’s mass into smaller columns. Those bowhunters who use Deep Six thread and inserts see improved blood trails, quicker game recovery, and complete pass-throughs. Meanwhile, the standard 8/32 arrow thread perfectly fits the common steel field points designed to fit all carbon and aluminum arrows. It is the same thread used by all arrow inserts available in the market.
