Value Collection 3720MSL Fillister Head Machine Screw 3/8-16

Product Description

The VALUE COLLECTION 3720MSL is a fillister head machine screw designed for general-purpose fastening applications in metal assemblies. Sized at 3/8-16 thread with a 1-1/4 inch length under head, this slotted-drive fastener is manufactured from steel with a zinc finish for corrosion resistance. It conforms to ASME B18.6.3 and SAE J82 standards, meeting Grade J82 material specifications. The fillister head profile offers a tall, narrow head that provides deep slots for secure driver engagement and recesses well into counterbored holes. This screw is a practical choice for maintenance, repair, and production work across mechanical and industrial settings.

This fastener suits applications where a fillister head is preferred for its self-centering driver contact and reduced footprint compared to a pan head. Common install scenarios include machinery frames, brackets, enclosures, and equipment panels. The 3/8-16 coarse thread provides strong clamping force in steel or tapped metal assemblies. Electricians, millwrights, HVAC technicians, and general trades use this style of fastener when servicing equipment that requires reliable, code-familiar hardware. Sold in individual packages with a minimum order quantity of 5 units.
