Stainless Steel Hex Head Bolts
What are stainless steel hex head bolts? Stainless steel hex head bolts are corrosion-resistant fasteners with a six-sided head, driven with a wrench or socket for use with a nut or in a tapped hole. Made from stainless, they resist rust in wet, coastal, and outdoor conditions across machinery, structural, and general assembly.
Stainless Steel Hex Head Bolts
Hex Tap Bolts
Corrosion-resistant fully threaded hex bolts in stainless for tapped holes and thin-material clamping where full engagement is needed.
Flange Bolts
Corrosion-resistant 18-8 stainless hex bolts with a built-in flange that spreads load and speeds assembly, no separate washer needed.
Hex cap screws, tap bolts, and flange bolts explained
The hex head family covers a few variations worth knowing. Hex cap screws are the precision standard for use with a nut or tapped hole, hex tap bolts are threaded the full length for shallow or tapped assemblies, and flange bolts add a built-in washer flange that spreads load and resists loosening. Choose the style that matches your joint, then match the grade to the environment, with 316 for coastal and saltwater work.
Why choose stainless steel hex head bolts
- Strong wrench grip: six-sided head drives with a wrench or socket.
- Corrosion resistance: holds up in wet and outdoor use.
- Versatile: works with a nut or in a tapped hole.
- Style range: cap screws, tap bolts, and flange bolts.
Common applications for stainless hex head bolts
- Machinery and equipment assembly

Stainless Steel Hex Head Bolts FAQ
What is the difference between a hex cap screw and a hex bolt?
Hex cap screws are made to tighter tolerances with a washer-faced head, while hex bolts are a looser general-purpose standard. The terms are often used interchangeably in retail.
Are stainless hex bolts strong enough for structural use?
Standard stainless is weaker than Grade 5 or Grade 8 carbon steel. For structural loads, verify the grade rating or step up in diameter.
How do I stop stainless hex bolts from seizing?
Use anti-seize on the threads and avoid high-speed driving. Stainless is prone to galling under friction and torque.
