Value Collection 6.M520BS Button Head Machine Screw

Product Description

The VALUE COLLECTION 6.M520BS is a fully threaded button head machine screw manufactured from stainless steel. The button head profile sits low and wide against the mating surface, making it well suited to applications where a flush or near-flush appearance matters. Drive engagement is through a pin-in hex socket, which requires a pin-in hex key or tamper-resistant bit to install or remove. This fastener is used across light fabrication, enclosure assembly, and equipment maintenance where corrosion resistance and a clean head profile are required. Installation is typically performed by machinists, millwrights, or maintenance technicians.

This screw is appropriate for use in both indoor and outdoor assemblies where stainless steel is specified for corrosion resistance. The fully threaded shank provides maximum thread engagement across the entire fastener length, which is useful in thin-material applications or where a nut is used rather than a tapped hole. Typical install scenarios include panel assembly, fixture mounting, and light-duty structural connections in environments exposed to moisture or mild chemicals.

Key Features

• Button head profile provides a low-profile, finished appearance at the fastener head
• Pin-in hex socket drive resists unauthorized removal with standard hex tools
• Fully threaded shank maximizes thread engagement across the full fastener length
• Stainless steel construction offers corrosion resistance for wet or outdoor environments

Compatibility

Designed as an OEM-style replacement or general-use fastener for applications specifying a button head pin-in hex socket machine screw in stainless steel.

Installation Notes

Installation requires a pin-in hex socket driver or tamper-resistant hex bit of the appropriate size. Power down or de-energize any equipment before accessing fastener locations on electrical or mechanical assemblies. Do not exceed the torque appropriate for the fastener diameter and material to avoid galling, which is common with stainless steel fasteners. Apply an anti-seize compound to the threads when fastening into stainless or aluminum tapped holes to prevent thread binding.
