Stainless Steel Hex Tap Bolts
What are stainless steel hex tap bolts? Stainless steel hex tap bolts are hex cap screws threaded the full length of the shank, used in tapped holes or shallow assemblies where full thread engagement is needed. Made from stainless, they resist rust in wet, coastal, and outdoor connections where a fully threaded hex bolt is required.
When full thread makes the difference
A hex tap bolt is fully threaded rather than having a plain shoulder under the head, which matters when the bolt threads into a tapped hole or clamps a thin stack where every bit of engagement counts. It also lets you adjust grip length by simply threading the nut to any point. Where a joint needs a smooth unthreaded shoulder for shear alignment, a partially threaded hex cap screw is the better pick. In stainless, use anti-seize on the long thread run and step up to 316 for coastal exposure.
Why choose stainless steel hex tap bolts
- Full thread engagement: threads the entire shank for tapped holes and thin stacks.
- Adjustable grip: nut can seat at any point along the shank.
- Corrosion resistance: holds up in wet and outdoor use.
- Grade options: 18-8, 304, and 316 for the right environment.
Common applications for stainless hex tap bolts
- Threading into tapped holes
- Shallow or thin-material clamping
- Machinery and equipment assembly
- Marine and coastal hardware (use 316)
For a partially threaded option with a shoulder, see stainless hex cap screws, and pair tap bolts with matching hex nuts and flat washers. Browse all finishes on the main hex tap bolts category.
Stainless Steel Hex Tap Bolts FAQ
What is the difference between a hex tap bolt and a hex cap screw?
A hex tap bolt is threaded the full length, while a hex cap screw is usually partially threaded with a plain shoulder under the head. Tap bolts suit tapped holes and thin clamping.
Can I use a hex tap bolt with a nut?
Yes. The full thread lets a nut seat anywhere along the shank, which also lets you fine-tune grip length.
Why choose 316 hex tap bolts?
316 adds molybdenum for superior resistance to salt and chlorides, making it the choice for coastal and marine connections.
