Hex Flange Machine Bolts

Flange machine bolts, also known as hex flange machine screws, incorporate a bearing face, or flange, that extends beyond the diameter of the head. This flange distributes the clamp load over a larger area. Some flange machine bolts feature locking serrations on the face of the flange that are designed to "lock," or bite, into the material being fastened to provide resistance to loosening. AFT offers a wide selection of metric and standard flange machine bolt sizes with lengths ranging from 1/4” up to 4”. AFT Fasteners is a distributor of hex flange machine screws and offers both convenient small package sizes as well as large bulk packaging. Many of our flange machine bolts require a quote, which allows us to offer the best prices. Please contact us today – our experienced sales team is ready to help!
