Left Hand Thread Grade 8 Tap Bolts Full Thread 3/4-10 X 3-1/2 are designed for high-strength applications requiring reverse-threading to resist loosening in dynamic assemblies. These bolts feature a Grade 8 alloy steel construction and a full-thread shaft for maximum engagement along the fastener length.

With a left-hand thread, these bolts tighten by turning counterclockwise and loosen by turning clockwise. Theyre ideal when paired with compatible left-hand threaded nuts or tapped holes in machinery, automotive, or industrial equipment.

Key specifications

• Thread direction: Left-hand thread
• Size: 3/4 in nominal diameter
• Thread pitch: 10 TPI (3/4-10)
• Length: 3-1/2 in
• Thread type: Full thread along the shaft
• Material: Grade 8 alloy steel (high strength)

Applications

• Heavy equipment and machinery assemblies where reverse-threading is required to prevent loosening
