5/8" x 3" Conquest Grade 8 Indented Fine Thread Flange Bolt With Plain Finish
When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.
5/8" Grade 8 Indented Flange Bolts - Fine Thread, High Strength, No Washer Needed
Conquest Grade 8 Indented Flange Bolts in 5/8" diameter are engineered for maximum strength and superior vibration resistance. With a fine thread profile (18 TPI), indented hex head, and an integrated flange, these bolts offer unmatched holding power in high-load applications, without the need for a separate washer.
h2>5/8" Grade 8 Indented Flange Bolts - Fine Thread, High Strength, No Washer NeededManufactured from high-strength, heat-treated alloy steel and built to SAE Grade 8 standards, these flange bolts deliver outstanding tensile strength and shear resistance. The fine thread increases surface contact, reduces the chance of loosening under vibration, and is ideal for torque-critical assemblies.
Key Features
- 5/8" Diameter Grade 8 Alloy Steel: Built for strength, longevity, and high-load performance.
- Indented Hex Head: Provides positive tool engagement for easy installation and removal.
- Integrated Flange: Eliminates need for separate washers while evenly distributing clamping force.
- 18 TPI Fine Thread: Improves torque retention and vibration resistance in demanding assemblies.
