Value Collection R63283260 Thumb Screw 1/4-20 Oval Head 18-8

Product Description

The VALUE COLLECTION R63283260 is an 18-8 stainless steel thumb screw with a 1/4-20 UNC thread and an oval head profile. Designed for hand-tightening applications where tools are not practical or accessible, this fastener provides secure, repeatable clamping without a driver. The 18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments. The oval head measures 0.55 inches in diameter and 0.64 inches in height, providing a comfortable grip surface. Overall length is 2 inches. This fastener is sold individually and is suited for maintenance, panel access, equipment enclosures, and general mechanical assembly tasks across HVAC, electrical, and plumbing service work.

This thumb screw is commonly used in trade and industrial settings where panels, covers, or access doors require frequent removal and reinstallation. It is appropriate for light to medium-duty clamping in enclosures, junction boxes, filter housings, and equipment frames where hand-tightening torque is sufficient. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards, making this fastener compatible with a broad range of tapped holes and standard hardware in residential and light commercial applications.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-adjacent environments
• 1/4-20 UNC coarse thread for broad compatibility with standard tapped hardware
• Oval head profile with 0.55 inch diameter and 0.64 inch height for comfortable hand grip
• 2 inch overall length suits a range of panel thickness and clamping depth requirements
• No-shoulder design for full thread engagement from head to tip
• Sold individually — no minimum bundle required

Compatibility

Designed for use in any application with a standard 1/4-20 UNC tapped hole where a hand-tightened stainless steel thumb screw is required.

Installation Notes

Installation requires no tools under normal hand-tightening conditions. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which can occur with stainless steel fasteners when cross-threading or overtightening. De-energize any electrical enclosure before removing or reinstalling panel fasteners. Do not use power tools to drive this fastener — apply hand torque only to prevent thread damage.
