Allen bolts come in different types to cater to diverse industrial needs. Stainless Steel Allen Cap Screws are particularly useful as they can be driven directly into bolt holes without needing a nut for fixation. Similarly, Stainless Steel Allen Head Screws are ideal for engine parts, tools, and equipment components, where the bolt head is often flush with or below the surface for a clean finish. For applications requiring an accessible head, Stainless Steel Button Head Allen Bolts are used, while Stainless Steel Countersunk Allen Bolts are preferred for flat-surface finishes where the bolt head remains hidden. These versatile fasteners are available in a range of diameters and lengths, tailored to suit specific standards and applications.
