Value Collection 353-0620-01 Button Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 353-0620-01 is a button socket cap screw engineered for applications where a low-profile fastener head is required alongside high clamping strength. Manufactured from alloy steel with a black oxide finish, this screw measures 3/8-16 thread size by 1-1/4 inches in length under the head. It features a Torx Plus IP45 drive — offering improved torque transfer and reduced cam-out compared to standard hex socket drives. The fastener meets ANSI/ASME B18.3 and ASTM F835 standards and carries a 3A thread fit class with right-hand UNRC threading. Licensed tradespeople and assembly technicians working in light fabrication, machinery, and mechanical assemblies will find this a dependable OEM-style fastener choice.

This button socket cap screw suits medium-duty mechanical assemblies where a flush or near-flush head profile is needed and clearance around the fastener head is limited. The black oxide coating provides mild corrosion resistance in dry or lightly oiled environments. Typical applications include panel mounting, fixture fabrication, machine guarding, and general industrial assembly. The 3/8-16 coarse thread engages efficiently in tapped steel and alloy workpieces. Minimum order quantity is 100 pieces; each unit is packaged individually.

Key Features

• Torx Plus IP45 drive (7/32 inch drive size) reduces cam-out and allows higher torque application
• Alloy steel construction with 39-44 HRC hardness rating for reliable clamping in demanding assemblies
• Black oxide finish provides mild corrosion resistance and reduces light glare on fastener heads
• Fully threaded 3/8-16 UNRC right-hand thread with 3A fit class for consistent engagement
• Low-profile button head at 0.199 inches head height suits installations with limited vertical clearance
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 3/8-16 x 1-1/4 inch button socket cap screw for use in tapped alloy steel, carbon steel, or compatible workpieces requiring a low-profile head fastener conforming to ANSI/ASME B18.3.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical assemblers using a Torx Plus IP45 bit driver. Confirm the mating thread is clean, properly tapped to UNRC 3/8-16 specification, and free of debris before driving the screw. Do not exceed the manufacturer torque specifications for the fastener grade; consult engineering references for the appropriate clamp load based on application. Black oxide fasteners in outdoor or high-moisture environments should be supplemented with a compatible thread lubricant or sealant to maintain corrosion protection.
