• Self-Threading fittings, have special tapered drive threads for fast production line installation in untapped hole, saving the tapping cost (use in heat-treated parts is not recommended).
• A leakproof permanent seal is formed because the installation force causes the material of the untapped hole to reshape conforming to the fittings contour.
• Thread forming fittings can be replaced by any standard threaded fitting or by another thread-forming fitting because it realigns damaged threads in existing holes.
• Spherical base forms leak-proof seal.
• Steel Fittings: Bodies made of AISI 12L14 steel, carbo-nitrated and case hardened.
• Fittings have 2 notches on the edge of the hex for easy identification.
• Concave head for easy disconnect.
• Completely universal.
• Ball in tip to keep out dirt.
• Enlarged inner passage admits more lubricant.
• Balanced action spring retracts easily to allow maximum lube flow and holds ball firmly in sealing position.

Note: Drill size is 3/8".
