About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Yield Strength: 100,000 psi
Hardness:
Inch sizes: Rockwell C25 (Hard)
Metric sizes: Rockwell C15 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Specifications Met:
Inch sizes: ASTM A108, ASTM A311
Metric sizes: ASTM A108, ASTM A311

Often called Stressproof, these rods are stress-relieved to minimize warping during machining. Containing more carbon and manganese than other easy-to-machine carbon steels, 1144 offers higher yield strength and hardness, even without further heat treatment. Use it to fabricate parts that require stress resistance.

Tight-Tolerance High-Strength Easy-to-Machine 1144 Carbon Steel Rods

Yield Strength: 100,000 psi
Hardness: Rockwell C22 (Hard)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: ASTM A108, ASTM A311

These rods are precision ground and held to a strict straightness tolerance, so they're all set for turning applications in your lathe. Often called Stressproof, they are stress-relieved to minimize warping during machining. Containing more carbon and manganese than other easy-to-machine carbon steels, 1144 offers higher yield strength and hardness, even without further heat treatment. Use it to fabricate parts that require stress resistance.

Ultra-Strength Easy-to-Machine 1144 Carbon Steel Rods

Yield Strength: 125,000 psi
Hardness: Rockwell C30 (Hard)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: ASTM A108

Also known as Fatigueproof, these rods have enhanced strength and resistance to breaking from repeated impact compared to High-Strength Easy-to-Machine 1144 Carbon Steel Rods. Containing more carbon and manganese than other easy-to-machine carbon steels, 1144 carbon steel offers higher yield strength and hardness, even without further heat treatment. Use it to fabricate parts that require stress resistance.

Removable Drill Bushings for Thin Metal

Unlike most bushings, these won’t buckle the material or distort the hole when installed in thin-gauge aluminum and steel plates. Insert them into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in place by a lock ring (sold separately).

For technical drawings and 3-D models, click on a part number.
