FAQ
What is the primary benefit of a 16mm hex bolt head size?
The primary benefit is the ability to apply higher torque during installation without damaging the bolt head. The larger surface area distributes the wrenching force more effectively, preventing rounding and ensuring a secure, tight fit for heavy-duty applications.
Are these bolts suitable for outdoor or marine environments?
Yes, when specified with the appropriate material and finish. We recommend our A4-80 (316 stainless steel) bolts or carbon steel bolts with a hot-dip galvanized (HDG) finish for superior resistance to corrosion in harsh outdoor, coastal, or chemical environments.
Can I order custom lengths or special markings?
Absolutely. We offer customization services for length, threading, and head markings (such as property class indicators). Contact our sales team with your specific requirements for a tailored quotation.
What standards do your 16mm hex head bolts comply with?
Our standard production complies with international norms including ISO 4014 (full thread), ISO 4017 (partial thread), and their DIN equivalents (DIN 933, DIN 931). We can also manufacture to other specific standards upon request.
How do I determine the correct grade (8.8, 10.9, etc.) for my application?
The grade selection depends on the required tensile strength and the nature of the load (static, dynamic, vibratory). Grade 8.8 is a common high-strength bolt, while 10.9 offers higher strength for more critical joints. Our technical team can help you select the optimal grade based on your engineering specifications.
