Frequently Asked Questions (FAQ)
Q1: What is the typical torque specification for a Grade 10.9, 17mm hex head bolt?
A: Torque values depend on the bolt's grade, lubrication, and thread pitch. For a standard M17, pitch 2.0 mm, Grade 10.9 bolt with light oil lubrication, a typical tightening torque ranges between 380-450 Nm. Always refer to engineering guidelines for your specific application, as under or over-torquing can compromise joint integrity.
Q2: Can you supply 17mm hex bolts in stainless steel for corrosive environments?
A: Absolutely. We offer 17mm hex head bolts in Austenitic stainless steel grades A2-70 (304) and A4-80 (316). These provide excellent corrosion resistance for marine, chemical, and food processing applications. Note that the mechanical strength differs from carbon steel grades.
Q3: What is the difference between a hex bolt (DIN 933) and a hex socket head cap screw?
A: A hex head bolt (like the ones described here) has an external six-sided head for use with a wrench or socket. A hex socket head cap screw has an internal hexagonal drive (Allen key) and a cylindrical head. The choice depends on space constraints, required aesthetics, and tooling availability.
Q4: Do you offer certification with the bolts?
A: Yes. We can provide material test certificates (MTC/EN 10204 3.1) upon request, which certify the chemical composition and mechanical properties of the batch, ensuring compliance with specified standards.
Q5: What are the packaging options for bulk orders?
A: We offer industry-standard packaging to ensure product protection during transit. Options include sturdy carton boxes, wooden crates, or palletized loads. All packaging can be labeled with part numbers, quantities, and barcodes as per your requirements.
