SEMS Screws
SEMS Pan Phillips screws consist of a pan-headed machine screw with a cross-recessed drive and a permanently attached, captive washer. The broad pan head combined with the captive flat or split-spring washer ensures even clamping pressure and reliable vibration resistance without the risk of omitted components. This configuration significantly accelerates assembly line throughput and prevents foreign object damage (FOD) in delicate electronic and avionics manufacturing.
Our pan phillips sems screws are available in a range of sizes, materials, and standards. Contact us for a detailed specifications sheet and competitive bulk pricing.
