Slotted Raised Countersunk Barrel Nuts

SKU: SB002 Category:

Slotted Raised Countersunk Barrel Nuts in stock

Barrel nuts, used with screws of the same thread diameter to clamp two or more pieces of material together. They feature a raised countersunk head, similar to the style usually found in light switches and plug sockets, with a slotted drive. Can be fastened with a standard flat blade screwdriver.

Available as standard in A1 stainless steel (material specifically designed for machining) and A4 stainless steel for applications requiring superior corrosion resistance in environments exposed to salt water, with certain sizes available in A2. We also stock socket countersunk barrel nuts, here.

Note: Head diameters differ slightly to Din 964 raised countersunk screws
