Features and Benefits
Knurled head types have a pattern of ridges that allow for easy gripping and tightening by hand. Knurled head types are common in applications requiring frequent fastening and unfastening.
Steel is strong and durable but less corrosion resistant than stainless steel. To improve its resistance to corrosion, it may receive additional finishes and coatings.
