Value Collection MS35206-221 Pan Head Machine Screw

Product Description

The VALUE COLLECTION MS35206-221 is a 4-40 UNC pan head machine screw manufactured to military fastener standard MS35206. Measuring 1 inch in length under head, this screw features a Phillips drive and is machined from steel with a yellow cadmium finish applied for corrosion resistance. Rated at Material Grade 3, it is suited for general-purpose mechanical assemblies where a compact, low-profile pan head is required. This fastener ships without a washer and is sold in minimum order quantities of 100 pieces per purchase. Maintenance technicians, assemblers, and trade professionals working with panel enclosures, equipment housings, and electrical boxes commonly install this type of fastener.

This screw is intended for use in applications that reference military specification MS35206, including light-duty mechanical assemblies in HVAC equipment panels, electrical control enclosures, and general industrial hardware installations. The 4-40 thread size and 1-inch under-head length make it appropriate for securing thin sheet metal panels, terminal boards, and component brackets where a standard Phillips driver provides adequate torque without risk of cam-out on Grade 3 steel.

Key Features

• Thread size 4-40 UNC for compatibility with standard 4-40 tapped holes and nuts
• 1 inch length measured under head for accurate stack-up planning
• Pan head profile distributes clamping load across a wider bearing surface than flat or oval heads
• Phillips drive accepts standard Phillips screwdrivers and bit tips
• Yellow cadmium finish provides corrosion and oxidation resistance
• Conforms to military fastener standard MS35206 for dimensional consistency

Compatibility

Designed as a direct-fit replacement or replenishment fastener for any assembly specifying a 4-40 UNC pan head Phillips machine screw to military standard MS35206, without washer, at 1 inch length under head.

Installation Notes

Install using a standard Phillips No. 0 or No. 1 screwdriver or bit. De-energize and lock out all electrical equipment before accessing enclosures or panels where this fastener is used. Apply torque appropriate for 4-40 Grade 3 steel thread engagement depth to avoid stripping the thread or the drive recess. Inspect mating tapped holes or nuts for cleanliness and proper thread condition before installation.
