Combo Head Sex Bolts - Zinc-Plated Steel

The most economical solution for mating fasteners.

Available from stock in 6-32 thru 5/16-18 sizes, in steel zinc and stainless steel materials. Female Barrels and Male screws and shoulder bolts are sold separately. Our male screws are manufactured to match the female barrels, and our male shoulder screws also match both the barrel and head dimensions. To properly identify the part we need the barrel diameter and length of the barrel from underneath the head.
