🔩 Speaker Shoulder Screws for Lenovo ThinkPad X1 Yoga Gen 4 and X1 Carbon Gen 7 (3 pcs) 🔩

🖥️ X1 Yoga Gen 4 / X1 Carbon Gen 7 | Speaker shoulder screws | M2 × L3.7+1.8 mm | 3 pcs

Set of 3 genuine screws for mounting the internal speakers in the Lenovo ThinkPad X1 Yoga Gen 4 laptop (types 20QF, 20QG, 20SA, 20SB). The screws come from a working device and are in very good condition: heads and threads undamaged. According to the Lenovo service manual, the same type of screw also holds the speakers in the ThinkPad X1 Carbon Gen 7 (types 20QD, 20QE).

⚙️ PRODUCT CHARACTERISTICS

These are not ordinary screws but special shoulder screws. Under the flat, wide Phillips head there is a smooth, thicker shank section, followed by a thinner thread, as shown in the photos. The thread carries a blue nylon patch that keeps the screw from loosening on its own. According to the Lenovo service manual (HMM X1 Yoga and X1 Carbon, section 1140 Speaker assembly near the built-in battery), the speakers next to the battery are fastened with "M2 × L3.7+1.8 mm, flat-head shoulder, nylon-coated" screws, black, tightened to 0.181 Nm. A plain M2 screw without the shoulder is not a proper substitute.
