- Hex cap screws are manufactured to tighter tolerances as compared to hex bolts.
- The washer face under the head provides a precision bearing surface.
- The chamfered point improves engagement with a nut or pre-tapped hole.
- Silicon Bronze: non-magnetic, corrosion resistant, and has good thermal and electrical conductivity.
- Offers superior corrosion resistant as compared to stainless steel and is stronger than brass.
