Holt’s stainless steel Slotted Head Countersunk Machine Screws (Also known as set screws) are threaded all the way to the head (unlike Bolts that are only partially threaded), and are countersunk so they will fit flush to a surface when the hole is countersunk to the correct size.
They are ideal for ensuring permanent fixtures stay permanent when tightened to the correct torque for the application. An added feature of Machine Screws is they can be easily dismantled unlike rivets or welding that is more permanent. Add to the fact they are stainless steel corrosion resistant and you have a durable and very useful Bolt for use on your boat or in a whole host of areas such as architectural metalwork, classic cars, petrochemical industry and swimming pools.
This is due to the fact that Holt Slotted Head Countersunk Machine Screws are made from AISI 316 stainless steel — the second most common grade (after 304); it is also known as A4 or marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. It is also used for food and surgical stainless steel uses due to the alloy addition of molybdenum that prevents specific forms of corrosion.
