Frienda 40 Pcs Black Oxide Steel Nylon Tip Set Screws 1/4"-28 x 0.500" Thread Length

Features: Constructed with quality steel as the core material, the screws maintain solid structural integrity after heat treatment. The robust steel body provides consistent holding force, enabling them to firmly secure components without deformation or failure, even in scenarios involving moderate pressure or repeated use. Beyond high temperature resistance, the black oxide coating offers effective corrosion resistance, shielding the screws from moisture, humidity, and mild chemical exposure. This protective layer reduces rust and oxidation, extending the service life of the screws and maintaining performance stability in indoor, outdoor, or industrial environments. Specifications: Material: alloy steel Color: black, white Size: about 1/4"-28 x 0.500" Package includes: 40 x Black oxide steel nylon tip set screws Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays. Small parts included, please keep them away from little kids to avoid swallowing risk

• The Kit Includes: 40 black oxide steel nylon tip set screws, featuring the practical size of 1/4"-28 x 0.500"; The generous quantity covers routine usage scenarios and unexpected replacement needs
