ASP Hilo Screw – 4.2*38/32 ( 5,000 per box )

Technical Specifications Screw Type: Hi-Lo . These feature a unique dual-thread design—one high thread and one low thread. This provides superior grip, reduces the risk of cracking the material, and increases pull-out strength. Drive Type: Phillips (PHIL) . Indicated by the cross symbol on the label. Head Style: Pan Head . This provides a flat bearing surface under the head, ideal for securing thin materials where you don’t want the head to sink in. Point Type: Blunt End . Unlike standard sharp-tipped screws, these have a flat tip, which usually means they are designed to be driven into a pre-drilled hole. Finish: Zinc CR3+ . This is a trivalent chromium plating that provides decent corrosion resistance while being more environmentally friendly than older hexavalent chrome finishes. Special Feature: Locking Nibs . These are small ridges under the head that “bite” into the surface to prevent the screw from vibrating loose.
