This 1/4-28 x 1/2 Alloy Steel Button Head Socket Cap Screw with Nylon Insert is intended for cataloged inch-size applications where a button head and nylon insert are both specified. Its nylon insert creates frictional thread contact during installation, so the screw can be considered where service conditions call for added loosening resistance.
Button head geometry is useful when clearance, appearance, and lower head height matter more than using a standard socket head cap screw profile. Typical uses include electronics enclosures, control panels, and access covers, where a precise socket fastener with a low rounded head can support compact machinery layouts. Review thread size, length, mating material, available drive access, and whether the nylon insert is appropriate before release to production or repair work.
Since 1962, Cold Headers has helped industrial buyers locate specialty socket screws, replacement sizes, and unusual catalog configurations. For adjacent selections, buyers often compare standard button head socket screws, flat head socket cap screws, and nearby lengths when checking head style, material, locking feature, thread size, or nearby lengths.
