How Can Pre-Assembled SEMS Screws Reduce Your Electronics Assembly Line Costs?

Our chamfered hex Phillips SEMS screws with pre-assembled A2 flat washers eliminate the need for separate washer handling, cutting assembly time by up to 40% in high-volume electronics manufacturing. With ISO-compliant inspection of all critical dimensions including recess penetration and washer diameter, you get consistent torque performance and reduced rework. Available in corrosion-resistant 304SS and 316SS materials ideal for consumer electronics. Contact us for samples and cost-per-assembly analysis tailored to your production volume.

With 45 years of fastener manufacturing expertise, we deliver SEMS screws that meet the demanding requirements of OEM manufacturers across electronics, automotive, appliance, and industrial equipment sectors. Our comprehensive quality control measures inspect critical measurement points including across the flat and corner dimensions, head height, recess penetration, length, major diameter, thread angle, pitch, and minor diameter for screws, plus outside diameter, height, and recess diameter for A2 washers. The pre-assembled washer configuration with 16mm outside diameter eliminates separate washer handling, reducing assembly time and labor costs while ensuring consistent fastening quality. Our production capabilities span head diameters from M1.6 to M16/#00 to #5/8 and lengths from 1/8" to 12"/3.175mm to 600mm, supporting diverse customization requirements.
