In applications where space is limited, a bolt with a smaller head diameter can be used. However, this may require additional support to prevent the bolt from pulling through the material.
The head diameter is often specified by a number, with higher numbers indicating larger diameters. For example, a bolt with a head diameter of “10” will have a larger head than a bolt with a head diameter of “8”.
Head Height: The Hidden Factor in Bolt Performance
Head height refers to the distance from the top of the bolt head to the start of the threads. It may seem like a minor detail, but it plays a crucial role in the performance of your bolt.
Why Head Height Matters
Head height affects the bolt’s:
- Strength: A higher head height provides more material to resist bending and twisting forces.
- Gripping Power: A higher head height creates a larger surface area for the washer, increasing its grip on the bolted material.
- Clearance: A lower head height allows the bolt to fit into tight spaces where there’s limited clearance.
Choosing the Right Head Height
The ideal head height depends on the application. For high-stress situations, opt for a bolt with a higher head height to maximize strength and grip. For low-stress applications or where clearance is limited, a lower head height may be more suitable.
Common Head Height Types
- Regular Height: Most common, provides a balance of strength and clearance.
