bolts and nuts in general industrial applications where parts are subject to corrosion

18-8 stainless steel offers good corrosion resistance and machines easily but will over time stain in coastal environments

1-14 x 5 1/2 Grade 5 Hex Cap Screw Zinc Plated

Hardness for plain and zinc plated washers is HRC 38-45 and HRC 26-45 for hot-dip galvanized washers per ASTM F436

#39 Heavy Duty Jobber Drill Bit (12) 7/8-14 Grade 5 Hex Cap Screws Zinc Plated bolts and nuts in general#39 Heavy Duty Jobber Drill Bit . Web construction is heavier than general purpose construction making it particularly suitable for cotter pin hole drilling and cross hole drilling in head of bolts. The heavy construction affords efficient drilling in stainless steel and other hard materials. The split point reduces the thrust requirements and minimizes walking.
