5/8-11 X 2 Hex Head Cap Screw Grade 5 Steel Zinc Plated (6232CH5) (100 Pack)

5/8-11 X 2 Hex Head Cap Screw Grade 5 Steel Zinc Plated (6232CH5) (100 Pack)

Cross Reference #:

• FS6232CH5

Features:

• Applications/Advantages: Has greater tensile strength than a Grade-2. Yield-to-tensile ratio is the lowest of all heat treated steels.
• Heat Treatment: Grade-5 cap screws shall be heat treated, oil or water quenched, at the option of the manufacturer, and tempered at a minimum tempering temperature of 800?F.
• Material: Medium carbon steel. Use of an alloy steel is also acceptable.
• Core Hardness: 1/4 through 1 in. diameter, all lengths: Rockwell C25 - C34. 1-1/8 through 1-1/2 in. diameter, all lengths: Rockwell C19 - C30.
• Surface Hardness: 1/4 through 1 in. diameter, all lengths: Rockwell 30N54 maximum. 1-1/8 through 1-1/2 in. diameter, all lengths: Rockwell 30N50 maximum.
• Proof Load: 1/4 through 1 in. diameter, all lengths: 85,000 psi. 1-1/8 through 1-1/2 in. diameter, all lengths: 74,000 psi.
• Yield Strength*: 1/4 through 1 in. diameter, all lengths: 92,000 psi. minimum 1-1/8 through 1-1/2 in. diameter, all lengths: 81,000 psi. minimum
• Tensile Strength: 1/4 through 1 in. diameter, all lengths: 120,000 psi. minimum 1-1/8 through 1-1/2 in. diameter, all lengths: 105,000 psi. minimum
• Elongation*: 14% minimum (all diameters)
• Reduction of Area*: 35% minimum (all sizes)
• Plating: See Appendix-A for plating information.
• *These properties are tested only on machined specimens when the testing machine cannot provide for full testing of the parts.
• **Product standards require the manufacturer?s head marking to appear on the top of all cap screws 1/4? diameter and larger.
