Value Collection 3TSBS96C100 Button Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 3TSBS96C100 is a button head socket cap screw designed for fastening applications that require a low-profile head and strong clamping force. Threaded 3/8-16 UNC with a 1-inch length under the head, it is driven by a 7/32-inch hex socket. The fastener is machined from 316 stainless steel with a bright, uncoated finish, providing corrosion resistance in wet, marine, and chemically exposed environments. It conforms to ANSI/ASME B18.3 and ASTM F837 standards with a Class 3A thread fit. Machinists, millwrights, maintenance technicians, and field service pros install this type of fastener across a wide range of mechanical assemblies.

This button socket cap screw suits applications where a standard hex cap screw head would protrude too far or interfere with adjacent components. The low-profile button head makes it a practical choice in equipment enclosures, pump housings, HVAC equipment panels, fluid system manifolds, and other assemblies requiring a flush or near-flush fastening surface. The 316 stainless steel material grade is preferred in coastal, outdoor, and chemical service environments where 304 grade may not provide sufficient corrosion resistance.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• 3/8-16 UNC thread form with Class 3A fit for precise, reliable engagement
• 1-inch length under head suits medium-depth fastening applications
• Button head profile minimizes protrusion in tight clearance assemblies
• 7/32-inch hex socket drive for use with standard Allen wrenches and hex bit drivers
• Bright, uncoated finish — no plating to chip, flake, or contaminate sensitive assemblies

Compatibility

Designed as a standard UNC replacement or service fastener compatible with any 3/8-16 threaded hole requiring a button head socket cap screw per ANSI/ASME B18.3.

Installation Notes

Installation requires a 7/32-inch hex key or socket bit driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. When installing in stainless-to-stainless applications, apply an anti-seize compound to reduce the risk of galling. Follow applicable mechanical or equipment manufacturer torque specifications for the assembly being serviced.
