Value Collection 011589BR Hex Socket Cap Screw 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 011589BR is a hex socket cap screw designed for heavy-duty fastening applications requiring a secure, high-strength threaded connection. This screw features a 1-1/2-6 UNC thread size and a 4.5-inch length under head, making it suited for thick-material assemblies or deep-reach clamping situations. Constructed from alloy steel with a black oxide finish, it provides increased surface hardness and moderate corrosion resistance compared to plain steel. The 1-inch hex drive socket head accepts standard hex keys and Allen wrenches for installation in confined spaces where bolt heads or external wrenches cannot be used. Licensed tradespeople, maintenance mechanics, and industrial fabricators are the primary installers of this fastener type.

This fastener is appropriate for structural assemblies, machine frames, heavy equipment, and industrial fixtures where a countersinkable, high-clamp-force screw is required. The fully threaded configuration provides consistent thread engagement along the full shank length, making it well suited for through-bolting and applications where maximum thread contact is needed. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming it is produced to recognized dimensional and mechanical property requirements for socket cap screws.

Key Features

• 1-1/2-6 UNC thread size for heavy-load fastening applications
• 4.5-inch length under head for deep-grip or thick-material assemblies
• Fully threaded shank provides maximum thread engagement
• Alloy steel construction for high tensile strength and durability
• Black oxide finish offers surface hardness and mild corrosion resistance
• 1-inch hex socket drive allows use in confined or recessed spaces
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fit hex socket cap screw for industrial assemblies requiring 1-1/2-6 UNC thread specifications per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using a calibrated torque wrench and the appropriate 1-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before engagement to prevent galling or cross-threading in alloy-steel applications. Follow applicable ASME or equipment manufacturer torque specifications for the fastener grade and application. Do not over-drive or use impact tools without confirming the fastener and joint are rated for that installation method.
