Monster Overview:
Equip your projects with Bulk #6-32 Button Head Socket Cap Screws from Monster Bolts — engineered for strength, precision, and reliability. Made from premium ASTM A574 alloy steel and finished with a thermal black oxide + oil coating, these screws combine high tensile strength with a smooth, professional appearance and mild oxidation resistance. The button head design offers a low-profile, rounded finish ideal for assemblies requiring both performance and a refined look.
Built to meet ASME B18.3 and IFI-111 standards, these socket screws are heat-treated for strength and consistency. All Monster Bolts black oxide socket fasteners are fully RoHS compliant and ship directly from our U.S. warehouse for fast, reliable delivery.
