Frequently Asked Questions (FAQ)
What is the difference between a 5/32 hex bolt and a hex cap screw?
In industrial contexts, the terms are often used interchangeably for fasteners with a hex head. Technically, "cap screws" are often manufactured to tighter tolerances and are intended to be threaded into a tapped hole, while "bolts" are used with a nut. Our 5 32 hex bolt product line meets the high standards typically associated with cap screws.
How do I select the correct strength grade (Grade 2, 5, or 8)?
Selection depends on your application's stress requirements. Grade 2 is for general-purpose, low-stress applications. Grade 5 offers medium strength and is common in automotive and machinery. Grade 8 provides the highest strength for critical, high-stress, and high-vibration applications. Our technical team can assist with this decision.
Can I get these bolts in stainless steel for outdoor use?
Absolutely. We offer A2-304 stainless steel for general corrosion resistance and A4-316 for superior resistance to salts and chemicals, making them ideal for marine, coastal, or chemical processing environments. Specify your need when inquiring.
Do you offer matching nuts and washers?
Yes. We provide full fastener kits and can supply hex nuts, lock nuts, flat washers, and lock washers in corresponding sizes, materials, and finishes to ensure complete joint compatibility and performance.
What are the packaging options for bulk orders?
We offer industry-standard bulk packaging such as 100-piece poly bags, 1lb/5lb boxes, or large cartons/boxes. We can also provide custom bar-coding, labeling, and vacuum-sealing per your warehouse or production line requirements.
