Value Collection 0503MSB 5-40 Binding Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0503MSB is a 5-40 machine screw with a binding head and slotted drive. It measures 3/16 inch in length under the head and is manufactured from steel with a zinc finish. The binding head style provides a low-profile bearing surface that resists pulling through thin materials, making it well suited for panel assembly, electrical enclosures, and instrumentation work. This screw conforms to ASME B18.6.3 and SAE J82 standards, confirming dimensional and mechanical consistency for production and repair applications. Installation does not require a washer. The fastener is sold individually with a minimum order quantity of 100 units.

This screw is used in light-duty mechanical and electrical assembly where a small-diameter, fine-thread fastener is required. Common applications include securing terminal strips, control panels, and small metal or plastic sub-assemblies in HVAC, electrical, and instrumentation systems. The 5-40 thread designation indicates a number 5 screw diameter with 40 threads per inch, typical of precision instrument and electronics work. Electricians, control-panel builders, and HVAC technicians will encounter this fastener in both OEM assembly and field repair contexts.

Key Features

• Binding head profile provides broad bearing surface for thin-material clamping
• 5-40 thread form with 40 threads per inch for fine-thread engagement
• 3/16 inch length under head suits shallow panel and enclosure applications
• Steel construction with zinc finish for basic corrosion resistance
• Conforms to ASME B18.6.3 and SAE J82 for dimensional compliance
• Slotted drive compatible with standard flat-blade screwdrivers

Compatibility

Designed as an OEM-style replacement or production fastener for assemblies requiring a 5-40 binding head slotted machine screw with a 3/16 inch length under head, per ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Use a flat-blade screwdriver sized to fit the slotted drive to avoid cam-out and slot damage. Confirm thread engagement depth in the receiving material before applying torque to prevent cross-threading in fine-thread applications. Power down or de-energize any electrical panel or enclosure before installing or removing fasteners in live assemblies, following applicable NEC guidelines. Do not substitute a coarse-thread fastener in a 5-40 tapped hole.
