Self-Sealing Hex Bolt - Hex Head - 18-8 Stainless Steel - 1/2"-13 Thread - 1" Long - Pack of 5

Used to fasten and join two components. Bolts are designed to be used with a nut to provide the tension needed to hold two items together. Hex bolts feature an external hex head that protrudes above the fastening surface for use with a ratchet wrench. This item is paired with a silicone o-ring that sits under the head to prevent leaks and seal out contaminants. 18-8 stainless steel, also commonly known as 304 or A2 stainless steel, has good chemical resistance and may be mildly magnetic.
