roundhead fastener

Listings include round-head push pins, Chicago (binding) screws, mini round-head brads (for paper and crafts), and round nails supplied with mini nail gun kits.

Some push-pin options are packed in reusable storage boxes; others are described as coming in clear reusable plastic containers for convenient storage.

Materials shown include stainless steel, steel (including nickel-plated carbon steel), general metal, and plastic (used for push-pin heads).

Push pins are pressed into boards by hand using their needle points; Chicago (binding) screws are tightened or removed with a screwdriver; and brads are pushed through a punched hole, after which their two legs are separated and bent to secure the material.

Several metal fasteners are described as rust-proof or corrosion-resistant; listings mention nickel-plated carbon steel and brass plating, both noted to provide rust, corrosion, and oxidation resistance.
