Description
Overview:
The Self Drilling Screws Sizes: 8-14 Hex - Assorted Box of 70 is a mixed selection of zinc‐plated steel fasteners for quick metal‐to‐metal fixing with no pre‐drilling. Each screw has a self‐drilling tip and a washer‐faced hexagon head for a secure clamp and a neat finish. Supplied in practical lengths for light to medium gauge steel, they suit everyday use with cordless drills or impact drivers fitted with the correct hex nut driver. The assortment covers common gauges (#8, #10, #12, #14) so you can pick the right size for trunking, channel, brackets, sheet metal and light fabrication work. Supplied under MPN 105 406, this set is a reliable choice for site work, workshop jobs and maintenance tasks where speed and consistency matter.
Key Features:
- Metal‐to‐metal self drilling design removes the need for pilot holes, speeding up installation and reducing bit changes
- Washer‐faced hex head spreads the load and helps prevent pull‐through on thinner sheet
- Bright zinc‐plated steel for wear resistance and improved corrosion protection in general indoor and sheltered outdoor use
- Clean, sharp drill points for consistent start and bite, helping reduce walking on smooth steel
- Assorted box of 70 pieces covering popular gauges and lengths for everyday tasks
- Sizes included (imperial with UK metric): 8 x 1" (25.4 mm); 10 x 1/2" (12.7 mm), 10 x 3/4" (19.05 mm), 10 x 1" (25.4 mm); 12 x 1" (25.4 mm), 12 x 1 1/2" (38.1 mm), 12 x 2" (50.8 mm); 14 x 2" (50.8 mm)
- Hex head allows positive drive with a nut setter, reducing cam‐out compared with Phillips or Pozi heads
- Suitable for use with most cordless drills and impact drivers when used with the correct socket
