Precision Engineering Behind M16 Through Bolts

M16 through bolts deliver 1,200 MPa minimum tensile strength, exceeding ASTM F3125 Grade A325 specifications. Recent stress tests demonstrate a 34% improvement in vibration resistance compared to standard hex bolts, with a fatigue limit of 650 MPa at 2 million cycles. The unique ribbed shank design increases friction grip by 22%, enabling secure installations in concrete (C30-C50) and structural steel applications.

FAQS on through bolts m16

Q: What is the standard drill size for M16 through bolts?

A: The recommended drill size for an M16 through bolt is typically 17.5 mm (or 11/16"). This ensures proper clearance for the bolt to pass through materials while maintaining structural integrity.

Q: How do I choose the correct drill bit for M16 through bolts?

A: Use a 17.5 mm (11/16") drill bit for standard M16 through bolt installations. Always confirm based on the bolt manufacturer’s specifications and material thickness to avoid misalignment.

Q: Can I use an 18 mm drill bit for M16 through bolts?

A: Yes, an 18 mm drill bit can work for M16 through bolts, but it may reduce clamping force. For precision, stick to 17.5 mm unless specified otherwise by the bolt supplier.

Q: What tools are needed to install M16 through bolts?

A: You’ll need a 17.5 mm drill bit, wrench or socket set, and a torque tool. Ensure the hole is clean and deburred before inserting the bolt and tightening.

Q: Why is drill size critical for M16 through bolt applications?

A: Proper drill size (e.g., 17.5 mm) prevents bolt binding and ensures even load distribution. Incorrect sizing can weaken joints or damage threads during installation.
