Hex Tap bolts, also known as fully-threaded hex bolts, feature a pointed end. They are designed to be used in a drilled or tapped hole where a cap screw or stud would be impractical, and they are useful in a variety of automotive and industrial applications. AFT supplies grades 2, 5, 8 and stainless steel tap bolts. Stainless steel bolts are made from 18-8 stainless steel and used in environments corrosive to carbon steel.
Grades 2, 5, and 8 Tap Bolts
Grade 2 Tap Bolts: A low carbon, hex head bolt with a machined point and fully threaded. Grade-2 bolts are made from AISI 1006 – 1025 or equivalent steel, and to be used in drilled and tapped holes that are threaded full length. They can be used instead of a stud or nut.
Grade 5 Tap Bolts: A fully threaded hex bolt made from AISI -1541 or equivalent medium carbon steel and heat treated. 4037 modified steel (alloy) is also acceptable. Grade-5 bolts are commonly used to mount motors to machinery or other automotive applications.
Grade 8 Tap Bolts: A tap bolt made from medium carbon alloy and heat treated. Grade-8 bolts are used in automotive and fleet industries where greater tensile strength is required that can be met by the Grade-5 bolt.
