Product description
Hex head bolts have a hexagonal-shaped head, which allows them to be tightened or loosened with a wrench or socket. This design provides a good balance between ease of use and strength. UNC (Unified National Coarse) refers to the threading type, which is a common standard for bolts used in North America. "Coarse" threads are wider and deeper than fine threads, making them faster to install and often more durable in softer materials. A2 stainless steel is an austenitic stainless steel known for its good corrosion resistance, strength, and general durability. It's commonly used for outdoor applications or in environments where the bolt might be exposed to moisture.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
