Button Head Socket Screws from Bolts Nuts Screws Online Australia
These screws feature a larger bearing surface, low-profile head, and easy installation using an allen key. Perfect for various applications, Button socket screws offer enhanced performance compared to traditional socket head cap screws.
With a larger bearing surface and lower head profile, they're ideal for situations where material thickness prevents countersinking or when a sleek decorative finish is desired. Drive them effortlessly with a hex key, also known as an Allen wrench or hex power bit.
While the tensile strength may not match socket head cap screws, they're twice as strong as machine screws. Fully threaded with uniform threads throughout the entire length, these screws ensure consistent performance and secure fastening.
Also known as Socket Button, Button Allen Head, Button Hex, Allan Bolt, or BHSS, these screws come in black or plain finish. Please note that the plain finish is unfinished, lacking a protective coating against corrosion, leading to eventual rusting over time.
Galling can occur with excessive pressure during tightening, particularly with stainless fasteners or other materials. To prevent galling, tighten the nut slowly without excessive pressure or apply a suitable lubricant to reduce friction.
Thread Pitch (Metric) refers to the distance between thread peaks along a screw or bolt, expressed in millimeters (mm). Fastener Length is measured from the surface where the fastener will be installed to the end of the fastener. Variations may exist between batches, so please confirm critical dimensions before ordering.
