- This product contains 50% glass fibre. The addition of glass fibres improves the heat deflection temperature, allowing the material to withstand higher temperatures before deforming under load.
- Glass-reinforced nylon has greater tensile strength, stiffness and impact resistance than unreinforced PA66.
- The composite also possesses superior hardness, surface durability, and wear resistance compared to PA66.
- Socket head bolts are tightened and loosened with a hex key. Also known as socket cap screws, hex socket screws.
Product Summary
This product contains 50% glass fibre. While the melting point remains largely unchanged, the heat deflection temperature of PA66+GF (glass fibre reinforced PA66) is superior to that of PA66, meaning that the composite can withstand higher temperatures before beginning to deform under load. The composite exhibits reduced moisture absorption, a significant improvement over PA66's susceptibility to moisture. Common applications include automotive components, industrial machinery and consumer goods where high strength and thermal resistance are required. Socket head bolts are also known as socket cap screws.

The residents at the Veterans Home loved taking these apart and putting them back together. I bought more for them.
Very happy with the quality of the item and the speedy delivery
Smooth fitting and easy to cut for shorter lengths if required.
good quality, item as described , arrived imperfect condition.
Quick delivery, but had to use super glue to stick as the adhesive was not strong enough, but otherwise, great product.
Better than expected. Very well packaged (inside and out)
