Description
Features
- 50x Bolts, 50x Nuts, 50x Washers. Material: PA 66 / 50% GF. Type: Pan Cross Head Bolts. Length: 20mm. Diameter: 4mm. Pitch: 0.7mm. Head diameter: 7.8mm. Head height: 3mm. SKU: 530.
- Our 50% glass fibre (GF) filled material has superior tensile, flexural and impact strength, enabling it to be used in load bearing applications.
- Glass fibre reinforcement was introduced to PA66 to improve its mechanical properties and thermal stability, enabling its use in demanding applications.
- The addition of glass fibres enhances the heat deflection temperature, enabling the material to perform reliably at elevated temperatures.
- Cross drive design for screwdriver installation and wide underside for even load distribution. Also known as cross-recess pan screws, pan head machine screws.
Product Summary
While the melting point remains largely unchanged, the heat distortion temperature of PA66+GF 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. Pan cross head bolts and screws are also known as plastic bolts and plastic screws.

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.
