These bolts have never left the warehouse, and are only being sold because there was a surplus remaining. Their original use was for structural support of plastic spools.
Here are the details:
• 11 inches in length
• 3/8 inch hex-head
• 1/8 inch diameter shaft
• Steel zinc plated to reduce weathering
• Course threads (10 per inch)
• Blunt end
Could easily use these on any wood or plastic project if a pilot hole was drilled first as these have a blunt end and would not self thread well.
PLEASE CONTACT WITH ANY QUESTIONS
