At Shamrock Express we often field questions about which type of fastener is best for individual jobs. In fact we get the question about the pros and cons of fine threaded fasteners so often we've put together a list of benefits and drawbacks to consider when choosing whether or not to use a fine threaded screw or bolt.

Benefits of Fine Thread Bolts and Screws

1.  They yield finer adjustments due to smaller lead angles.
2.  They allow for higher tensile strength due to their shallow thread depth.
3.  They require less torque to tap hard materials due to thinner threads.
4.  They can engage in thinner materials due to increased thread contact.
5.  They can thread into thinner side walls due to a shorter thread depth.

Drawbacks of Fine Thread Bolts and Screws

1.  Thinner threads increases the chances of cross threading.
2.  They are more likely to strip when installed into weak materials.
3.  Thinner threads are more susceptible to becoming damaged.
4.  Smaller thread allowances require a thin plating.

Fine thread screws and fine thread bolts are available on the Shamrock Express website and ship nationwide daily.
