Why Our Carriage Bolts Outperform the Competition

Your projects demand rugged hardware that won't quit. Our 5/16 x 1-1/2 carriage bolt solutions deliver unmatched strength. How? We start with American-made SAE Grade 5 steel. Then apply triple-layer zinc plating. This combination resists corrosion 4X longer than standard bolts. Feel that satisfying snap when installing? That's precision threading engineered for perfect friction-lock. No more vibrating loose under stress!

Head-to-Head: Carriage Bolt Comparison

Generic hardware stores can't match our performance. Compare these critical specs:

Specification	Our 5/16 x 1-1/2	Standard Hardware Store
Material Grade	SAE Grade 5	Grade 2 (or unrated)
Plating Thickness	0.0008" (Class 8)	0.0002" (basic)
Shear Strength	7,200 lbs	4,100 lbs
Torque Tolerance	±5%	±15%

Notice the difference? Our 3.5 inch carriage bolt range undergoes ultrasonic testing too. This guarantees zero internal defects. Why risk project failure with cheaper bolts?

FAQS on 5 16 x 1 2 carriage bolt

以下是根据要求创建的5组英文FAQs，使用HTML富文本格式：

Q: What are the dimensions of a 5/16 x 1-1/2 carriage bolt?

A: A 5/16 x 1-1/2 carriage bolt has a 5/16-inch diameter shank. Its underhead length measures 1.5 inches. This size is common for light-duty wood-to-wood fastening.

Q: How does a 3/8 x 9 carriage bolt differ from standard sizes?

A: The 3/8 x 9 carriage bolt features an extra-long 9-inch shank. It's designed for thick material assemblies like timber framing. The 3/8-inch diameter provides greater shear strength than smaller variants.

Q: What applications require a 3-inch carriage bolt?

A: 3-inch carriage bolts are ideal for medium-thickness joints in decking or furniture. They secure materials up to 2-1/4 inches thick when combined with a washer and nut. Their dome head prevents pull-through in soft woods.

Q: Can I get zinc-plated 3.5 inch carriage bolts?

A: Yes, 3.5-inch carriage bolts commonly come with zinc plating. This coating provides corrosion resistance for outdoor use. Always specify "hot-dipped" for maximum weather protection.

Q: Do all carriage bolts have square necks?

A: Yes, carriage bolts feature a square section under the dome head. This design locks into materials during installation, preventing rotation. The mechanism works best in wood or soft metals.
