Value Collection R52001026 Hex Machine Screw 1/4-20 X 3/8 in

Product Description

The VALUE COLLECTION R52001026 is a 1/4-20 hex head machine screw designed for general fastening applications in mechanical, structural, and industrial assemblies. It measures 3/8 inches in length under the head and features a hex drive for use with standard hex wrenches or sockets. Constructed from steel with a zinc plating finish, this fastener resists corrosion in light-duty environments. The external tooth washer style provides positive locking under the head to resist loosening from vibration. This screw conforms to ASME B18.13a and SAE J82 standards and carries a Grade J82 material designation, making it suitable for applications requiring consistent mechanical performance.

This fastener fits a wide range of light industrial, HVAC, electrical, and mechanical assembly applications where a 1/4-20 thread pitch is called for. The external tooth configuration makes it well suited for installations subject to vibration, such as panel mounting, equipment enclosures, and bracket attachments. Trades including HVAC technicians, electricians, and mechanical contractors commonly use this screw when securing components in conduit systems, control panels, and equipment frames. It is sold in multiples of 100 units per order.

Key Features

• 1/4-20 UNC thread with 3/8 inches length under head for precise fitment in standard fastener applications
• Hex head and hex drive for reliable torque with standard wrenches or socket tools
• External tooth washer style locks the fastener in place under vibration without a separate washer component
• Zinc-plated steel construction provides corrosion resistance in light-duty and indoor applications
• Meets ASME B18.13a and SAE J82 standards for dimensional and material consistency
• Grade J82 material designation confirms mechanical property compliance for general fastening use

Compatibility

Designed as a standard inch-system machine screw for use in any application requiring a 1/4-20 thread pattern with a hex head and external tooth locking washer feature, including panel assemblies, equipment enclosures, and mechanical brackets.

Installation Notes

Install using a hex wrench or socket driver sized for a 1/4-inch hex head. Power down or de-energize any electrical panel or equipment before driving fasteners into live assemblies. Do not overtighten into thin sheet metal or plastic substrates, as the external tooth profile may cause surface damage if excessive torque is applied. Follow applicable mechanical or electrical codes, such as NEC guidelines, when using fasteners in electrical enclosure applications.
