Description

APC HC0271 1/4-20 x 0.19″ Cup Pt., 18 SHSS

The APC HC0271 1/4-20 x 0.19″ Cup Point Socket Head Set Screw represents a dependable fastening solution designed for applications where secure, precise, and high-pressure holding strength is essential. Manufactured to rigorous quality standards, this set screw is crafted to offer exceptional reliability in mechanical assemblies, equipment adjustment mechanisms, and industrial components that rely on controlled fastening without the need for protruding bolt heads. The 1/4-20 thread size provides a balanced combination of strength, compactness, and versatility, making it suitable for a wide variety of installations in both consumer-grade and professional-grade environments.

This model features a cup point, which is one of the most widely used point styles for set screws. The cup point includes a shallow, hollowed-out tip designed to penetrate slightly into the surface of the mating part, thereby enhancing gripping ability and preventing slippage under torque, vibration, or movement. This structural design allows the screw to apply consistent pressure while maintaining alignment of shafts, collars, pulleys, gears, and other rotary components. The cup point’s shape works especially well in semi-permanent settings or applications requiring repeated tightening, ensuring a secure hold while minimizing surface marring compared to sharper point types.

Built as a socket head set screw (SHSS), the APC HC0271 uses a hex-drive interface that enables easy installation and removal using a standard hex key or Allen wrench. This interface allows installers to achieve greater torque compared to slotted or Phillips-type screws, making it ideal for precision mechanisms, tight assembly spaces, and situations where the screw must be recessed completely into a threaded hole. The 18 SHSS designation refers to the series and structural classification of this fastener within APC’s product line, indicating consistent engineering specifications and quality requirements.

The screw measures 0.19 inches in length, making it a compact and practical option for installations requiring short fastening depth without sacrificing clamping power. Its smaller length is well suited for fine adjustments, locking components into position, and securing parts where excess protrusion could cause interference with moving machinery or alignment surfaces. Applications in robotics, manufacturing installations, electronics housings, automotive assemblies, and tool fixtures commonly utilize set screws of this size because of their strength-to-size efficiency and minimal spatial footprint.

In terms of material and construction quality, APC’s fasteners are engineered for durability, corrosion resistance, and long operational life. Although the exact material composition may vary by batch specifications, APC typically manufactures set screws from high-grade alloy steel hardened for strength, resilience, and wear resistance.

Automatic Pool Covers, Inc. took its first steps into the industry in 1979 as a small pool cover distributor. They continued to grow exponentially into the millennium, becoming a leader of the cover distributor industry. As continued to grow, they began to use their vast knowledge of the industry to develop and experiment with their own designs with the hope of making the most efficient, convenient and sturdy product.
