Hillman 880643 Class 8.8 Metric Hex Cap Screw M4-0.70 x 50mm, 2-Pack

Class 8.8 Metric Hex Cap Screws are bolts with hexagonal heads and machine threads for use with a nut or in a tapped hole. A common feature on hex cap screws is a washer surface directly under the head which creates a better seal.

Features:

• MADE USING CLASS 8.8 STEEL: Appropriate for most general use (match with Class 8.8 washers and nuts)
• PARTIALLY THREADED SHANK: Allows for a stronger grip between objects and less shear movement
• CORROSION-RESISTANT FINISH: Heat-treated zinc combines lasting durability with strong corrosion protection
• HIGH-TORQUE DESIGN: Hex cap head and machine threads combine to offer higher torque capability
• Washer surface directly under head creates better seal
