Standard M6 Hex Cap Screws Bolts Steel Nickel Fastener Mowers Parts G401237 Fits Jacobsen
Description
Hex cap screw is also known as hex bolt . Normally . it has a hexagonal head with chamfer edges for hex socket wrench or spanner rotating during operation , machine thread style is fine or course and the threaded length is about 2/3 of total shaft length for the lengths over 70 mm .
Specification
| Description | Charicteristic |
| Zinc | Various color can be choosed and perfect on anti-corrosion |
| Nickel | Make the surface of the screws more bright and hardened and the performance of screws will be improved |
| Polish | Improving the brightness of surface but is inferior is not as zinc in anti-corrosion |
| Tin | it is very perfect to be anti-rust , and widely used to components |
| Brass | It is usually used with Nickel for more good anti-corrrosion. |
| Dacromet | Is used for screws with big sizes and can stop screws to be rusted long time even under bad surroundings . |
| Passivation | A little dark on the surface , good corrosion resistance |
Characteristics
Wear resistance
Plastic hexagon nuts have higher hardness 118 after improved chemical elements .
Good self-lubricant
Self lubricant make plastic hexagon nuts are more resistant wear and a longer service .
