Multiquip 12287 Screw THP 1/4-20 X 3/4 SS

The Multiquip 12287 is a genuine OEM Screw THP 1/4-20 X 3/4 SS designed for a wide range of Multiquip and Whiteman equipment, including STX, HTX, HHN, JWN, and WT series machines. As a direct OEM replacement, this stainless steel screw delivers the exact thread pitch, head profile, and material grade specified by Multiquip for original equipment assembly. It is verified for use across ride-on trowels, walk-behind trowels, pavement saws, concrete saws, light towers, water trailers, and core drills. Trust the 12287 to restore your equipment to proper operating condition without adaptation or guesswork.

Key Features

• Stainless Steel Construction — 304-grade or equivalent stainless material resists corrosion and maintains clamping strength even in wet or outdoor conditions common to concrete finishing and saw operations.
• Correct Thread Specification — 1/4-20 UNC thread form and 3/4 in. length match the OEM-specified fastener dimensions, ensuring full thread engagement in tapped bores across multiple Multiquip assemblies.
• Broad Cross-Equipment Compatibility — Fits STX, HTX, HHN, JWN, and WT series machines, as well as SP and PS pavement saws, FS concrete saws, LT light towers, and KD core drills.
• Genuine OEM Sourcing — Supplied directly under Multiquip part 12287, so head geometry, drive type, and material grade match the fastener that left the factory.
• Secure Panel and Guard Retention — THP (truss head Phillips) profile distributes clamping load across a wide bearing surface, keeping covers, guards, and frames seated firmly under vibration.

A THP (truss head Phillips) machine screw provides a wide, low-profile domed head that spreads clamping load over a larger surface area compared to a standard pan-head fastener. This geometry is commonly used to secure sheet-metal panels, guards, and enclosures where flush mounting and broad load distribution are needed. Stainless steel construction prevents the galvanic corrosion and thread seizure that can occur when standard steel fasteners are used in moisture-exposed or chemically active environments. When a fastener in this position is stripped, broken, or missing, panels can shift, guards can loosen, and access covers may fail to seal correctly — making prompt replacement with the correct OEM specification important for both machine integrity and operator safety.
