Value Collection 1-EFL-10-17- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFL-10-17- is a winged iron thumb screw designed for hand-tightening applications where tools are not practical or necessary. Manufactured from iron with a zinc-plated finish for basic corrosion resistance, this thumb screw features a 3/8-16 UNC thread and a shouldered body configuration. The winged head allows for firm finger grip during installation and removal. With an overall length of 1-7/8 inches and a length under head of 1 inch, it suits a range of light-duty fastening tasks encountered in mechanical assemblies, equipment panels, and access covers.

This thumb screw is suited for use in residential and light commercial settings where frequent hand access is required — such as service panels, enclosures, jigs, fixtures, and equipment guards. The 5/8-inch shoulder diameter and 3/8-16 UNC thread make it compatible with standard tapped holes of the same thread specification. Plumbers, HVAC technicians, electricians, and general maintenance trades commonly use winged thumb screws when securing access covers or panels that require routine removal without tools.

Key Features

• Winged head design allows hand-tightening and loosening without tools
• 3/8-16 UNC thread standard for compatibility with common tapped holes
• Zinc-plated iron construction provides basic corrosion resistance
• Shouldered body configuration for precise seating in clearance holes
• 1-11/16 inch head diameter offers a wide gripping surface for positive hand torque
• Compact 1 inch length under head suits thin panel and enclosure fastening

Compatibility

Designed as a standard 3/8-16 UNC winged thumb screw for use in any application requiring a tapped hole of matching thread specification. No specific system or model compatibility is stated by the manufacturer for this fastener.

Installation Notes

Installation requires no special tools — thread the screw by hand into a properly tapped 3/8-16 UNC hole. Ensure mating threads are clean and free of debris before installation to avoid cross-threading. Do not use power tools to drive this thumb screw, as the winged head is not rated for tool-driven torque and the iron construction may be damaged. Follow applicable equipment manufacturer guidelines when securing access panels or covers.
