SEMS Screw Philips Pan Head Double Washer Flat Spring

SEMS screw combines two separate parts into one pre-assembled, low-cost fastener. With washers under the head, the washer can be spring or flat or internal/external threaded washer. SEMS screw is fast, permanent, and easily adaptable to many applications. The Phillips screw drive was created by John P. Thompson, who after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent expired in 1966, but the Phillips Screw Company continued to develop improved designs. Ever Hardware provides custom-made fasteners and customizable packaging.
Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
