Hex Head Cap Screws
U-Bolt-It is a leading supplier of hex head cap screws for a variety of applications including medical equipment, oil field equipment, aerospace and construction. Hex bolts, commonly referred to as hex head cap screws, are bolts with a hexagonal (six sided) head. Hex cap screws create a better seal from the washer surface being directly under the head.
At U-Bolt-It, we manufacture hex bolts in almost any material, size and length, but we always stock a full product line of hex head cap screws including 18-8 & 316 stainless steel, AISI 304 & AISI 316 stainless steel, A193 B7, 718 Inconel, B8 & B8M and more. The sizes of hex bolts we carry range from ¼ inch to up to 3 inches. We also offer high quality galvanized or zinc plated coatings for our cap screws.
